Mobile Car Air Conditioning Perth recently attended a Mitsubishi in Northbridge with an unusual air conditioning problem. The system produced cool air, but it wasn’t getting properly cold. The owner also told us that the air conditioning would sometimes stop working completely.

CMM Automotive carried out a series of tests to find the cause.

Our nitrogen pressure test detected refrigerant leaking from the air conditioning Schrader valves. We replaced both leaking valves and charged the system with the correct amount of R134a refrigerant.

At first, everything appeared to work correctly.

However, we allowed the Mitsubishi to continue running. About 20 minutes later, the vents suddenly started blowing hot air.

Further diagnosis found a second fault. An electrical relay would heat up after operating for some time and then stop working.

Mitsubishi Air Conditioning Not Cold Enough

Air conditioning problems aren’t always straightforward.

The customer’s description can provide important information before testing even begins.

In this case, the Mitsubishi had two symptoms. The air wasn’t getting cold enough, and the system would sometimes stop working.

That second symptom was particularly important.

An air conditioning system that works and then suddenly stops can have an electrical or control problem. However, we still needed to test the entire system.

Nitrogen Testing Found Refrigerant Leaks

CMM Automotive pressure tested the Mitsubishi’s air conditioning system with nitrogen.

The test identified leaks from the Schrader valves.

Schrader valves provide service access to the air conditioning system. Like other seals and components, they can eventually develop leaks.

Even a small leak can allow R134a refrigerant to escape over time.

We replaced both faulty Schrader valves before continuing with the air conditioning service.

Recharging the System With R134a Refrigerant

After repairing the leaks, we charged the Mitsubishi’s air conditioning system with the correct amount of R134a refrigerant.

The system initially operated correctly.

Cold air began coming from the vents, and the repair appeared successful.

However, the owner’s original complaint included an important detail. The air conditioning sometimes stopped working.

For that reason, we didn’t finish our testing as soon as the system began producing cold air.

We allowed the vehicle and air conditioning system to continue running.

That decision helped us find the second problem.

Aircon Suddenly Started Blowing Hot Air

About 20 minutes later, the Mitsubishi’s air conditioning suddenly started blowing hot air.

We now had the intermittent fault happening while we were testing the vehicle.

This allowed us to continue diagnosing the problem.

Further electrical testing identified a faulty relay.

The relay worked when it was cold. However, it became hot after operating for a period of time. Once the relay heated up, it stopped functioning correctly.

The air conditioning then stopped producing cold air.

Why Intermittent Aircon Faults Can Be Difficult to Find

An intermittent fault may not appear when a mechanic first tests the vehicle.

The system might work perfectly for five or ten minutes. The problem may only occur once components reach operating temperature.

This can make diagnosis more difficult.

If we had tested this Mitsubishi for only a short period, we could have missed the faulty relay.

The customer may have driven away with cold air, only for the same problem to return later.

Allowing the system to operate for longer reproduced the owner’s original complaint.

Two Different Air Conditioning Faults

This Mitsubishi had two separate air conditioning problems.

The leaking Schrader valves allowed refrigerant to escape. We needed to repair those leaks and restore the correct R134a charge.

The faulty relay caused a completely different problem.

Once the relay became hot, it stopped working and affected the air conditioning operation.

Repairing only the refrigerant leak would not have solved the customer’s entire complaint.

This is a good example of why professional car air conditioning diagnosis in Perth matters.

Why We Test Before and After Aircon Repairs

CMM Automotive doesn’t simply identify one problem and assume the job is complete.

Testing the system after repairs can reveal other faults.

We check air conditioning performance and vent temperatures. We also make sure the system continues operating correctly.

This becomes especially important when the customer reports an intermittent problem.

The information the owner provides can help us reproduce the fault and identify its cause.

We bring professional air conditioning equipment directly to your home or workplace.

Our services include leak detection, nitrogen pressure testing and system performance checks. We also diagnose compressor and electrical faults.

Our goal is to find the cause rather than simply treat the symptom.

Does Your Car Aircon Work and Then Stop?

If your air conditioning starts cold but later blows warm or hot air, an intermittent fault may be causing the problem.

Don’t automatically assume that the system simply needs more refrigerant.

CMM Automotive provides Mobile Car Air Conditioning Perth services for many common and intermittent aircon faults.

We can test the system, identify the problem and explain the appropriate repair.

Frequently Asked Questions

Why does my car aircon work and then suddenly blow hot air?

Electrical faults, compressor problems and other control issues can cause intermittent air conditioning operation. Proper testing can help identify the cause.

Can Schrader valves leak aircon refrigerant?

Yes. Worn or damaged Schrader valves can allow refrigerant to escape from the air conditioning system.

Why should an aircon system run after repairs?

Running the system allows the technician to check its performance. It can also help reveal faults that only appear after components become hot.

Does CMM Automotive diagnose intermittent aircon faults?

Yes. CMM Automotive diagnoses many electrical, refrigerant and mechanical air conditioning problems throughout Perth.

Mobile Car Air Conditioning Perth recently attended a Volkswagen in Edgewater because the air conditioning vents were not blowing cold air. At first, the symptoms could easily suggest low refrigerant or another common aircon fault.

CMM Automotive tested the system before recommending any repairs.

Our initial vent temperature test confirmed that the air entering the cabin wasn’t cold enough. However, testing under the bonnet showed that the vehicle’s air conditioning system was operating correctly.

The system contained the correct amount of R134a refrigerant and showed no signs of a refrigerant leak.

Further diagnosis found the real problem inside the vehicle. The interior air flaps were not closing off the heater correctly. This allowed hot air to mix with the cold air before it reached the vents.

VW Air Conditioning Blowing Warm Air

Warm air from the vents doesn’t always mean that the refrigeration system has failed.

A vehicle’s air conditioning system has several components working together. The compressor circulates refrigerant through the system. Other components remove heat and help produce cold air.

However, producing cold air is only part of the process.

The vehicle must also control where that air travels and how much heat mixes with it.

This is where the interior HVAC system becomes important.

Testing the Volkswagen Air Conditioning

We started by checking the temperature of the air coming from the VW’s interior vents.

The vent temperature confirmed the customer’s complaint. The air wasn’t getting cold enough.

We then continued testing the air conditioning system under the bonnet.

The refrigeration side of the system was working correctly. It also contained the correct amount of R134a refrigerant.

Our testing found no refrigerant leaks.

This information allowed us to look beyond the usual causes of poor air conditioning performance.

The VW Didn’t Need an Aircon Regas

Many drivers assume that warm air means their vehicle needs an air conditioning regas.

This Volkswagen shows why that isn’t always true.

Adding more refrigerant would not have fixed the problem. The system already contained the correct refrigerant charge.

Adding unnecessary refrigerant can also create further problems.

Instead, we continued diagnosing the system to find out why cold air wasn’t reaching the cabin correctly.

Interior Air Flaps Causing the Problem

Further testing identified a problem with the interior air flaps.

The HVAC system uses internal doors or flaps to control airflow and temperature. These flaps help direct air through different parts of the heater and air conditioning system.

When the driver selects a cold temperature, the system should limit unwanted heat from entering the airflow.

The flaps in this Volkswagen were not closing off the heat correctly.

As a result, warm air mixed with the cold air produced by the air conditioning system. By the time the air reached the dashboard vents, it was no longer cold enough.

Why Aircon Diagnosis Is Important

This VW in Edgewater provides a good example of why proper car air conditioning diagnosis in Perth matters.

The obvious symptom was warm air from the vents.

A quick assumption might have led someone to regas the system. However, a regas would not have solved this fault.

We checked the refrigerant level and system operation first. Those tests showed that the air conditioning components under the bonnet were doing their job.

That allowed us to investigate the interior temperature control system.

Finding the actual cause prevents unnecessary work and expense.

What Are Car Air Conditioning Blend Doors?

Many people call them air flaps, blend doors or temperature doors.

These components sit inside the vehicle’s HVAC housing. They control how air moves through the heating and air conditioning system.

Depending on the vehicle, electric actuators may move these doors when the driver adjusts the temperature controls.

If a flap sticks or fails to move correctly, the system may mix too much heated air with the cold air.

The result can feel exactly like an air conditioning system that isn’t cooling properly.

Aircon Not Cold Doesn’t Always Mean Low Gas

Refrigerant levels are important, but they are only one part of air conditioning diagnosis.

A vehicle can have the correct refrigerant charge and still blow warm air.

Compressor control problems, electrical faults and airflow issues can all affect performance. Interior temperature doors can also cause problems, as we found with this Volkswagen.

Testing helps separate these faults from a genuine refrigerant problem.

That’s why CMM Automotive diagnoses the system before recommending a repair or regas.

CMM Automotive provides mobile car air conditioning diagnosis in Edgewater and across the Perth metropolitan area.

We bring professional diagnostic equipment directly to your home or workplace.

Our services include vent temperature testing, refrigerant leak detection and system performance testing. We also diagnose compressor, electrical and temperature control problems.

Our goal is to find out why the air conditioning isn’t working correctly.

Car Aircon Not Blowing Cold?

If your vehicle’s air conditioning isn’t cold enough, don’t automatically assume that it needs more refrigerant.

The problem may come from another part of the system.

CMM Automotive provides Mobile Car Air Conditioning Perth services for a wide range of aircon faults.

We can test the system, identify the likely cause and explain the appropriate next step.

Frequently Asked Questions

Why is my car aircon warm when it has enough refrigerant?

Several faults can cause this problem. Interior air flaps, electrical controls and other HVAC components can affect the temperature at the vents.

What does an aircon blend door do?

A blend door controls how much heated and cooled air enters the cabin. A faulty door can cause warm air from the vents.

Does warm air always mean my car needs a regas?

No. This Volkswagen had the correct R134a charge and no refrigerant leaks. The problem came from the interior air flaps.

Does CMM Automotive provide mobile aircon diagnosis in Edgewater?

Yes. CMM Automotive provides mobile car air conditioning diagnosis throughout Edgewater and the Perth metropolitan area.

Mobile Car Air Conditioning Perth recently attended a Jeep in Balga with an air conditioning system that was no longer working correctly. The owner had no effective air conditioning and needed the system professionally diagnosed.

CMM Automotive attended the Jeep and carried out several tests at the vehicle’s location.

The system initially passed a vacuum test without showing an obvious problem. However, we continued testing rather than assuming the system was leak-free.

A nitrogen pressure test produced a different result. We used our air conditioning analyser at the interior vents and detected refrigerant coming through the dash area.

This indicated a leak within the air conditioning system behind the dashboard.

Jeep Air Conditioning Not Working

A car air conditioning system can stop cooling for many reasons.

Low refrigerant is a common cause. However, refrigerant doesn’t simply disappear from a sealed system without a reason.

A leak may develop in the condenser, hoses, seals or other air conditioning components. Leaks can also occur within components located behind the dashboard.

Finding these leaks can require more than one type of test.

This Jeep in Balga provided a good example.

Vacuum Testing the Jeep Air Conditioning System

CMM Automotive began by vacuum testing the air conditioning system.

Vacuum testing forms an important part of air conditioning diagnosis and servicing. It can help identify leaks before charging the system with refrigerant.

In this case, the Jeep showed no obvious problem during the vacuum test.

It would have been easy to stop testing at this point.

However, we wanted to make sure the system could also hold pressure correctly.

Nitrogen Pressure Testing Found the Problem

We then pressure tested the Jeep’s air conditioning system with nitrogen.

Nitrogen testing allows us to place the system under positive pressure. This can expose leaks that may not appear during a vacuum test.

The pressure test gave us the information we needed.

We then used an air conditioning refrigerant analyser at the Jeep’s interior vents. The analyser detected refrigerant coming through the dash vents.

This result indicated a refrigerant leak behind the dashboard.

Why Would Refrigerant Come Through the Air Vents?

The evaporator forms part of the vehicle’s air conditioning system and normally sits inside the HVAC housing behind the dashboard.

Air passes across the cold evaporator before travelling through the vents and into the cabin.

A leak in this area can allow traces of refrigerant into the HVAC housing. The blower fan may then carry those traces through the interior vents.

Using suitable electronic detection equipment at the vents can help identify this type of hidden leak.

Without proper testing, finding a leak behind the dashboard can be difficult.

Why Different Aircon Tests Matter

This Jeep demonstrates why CMM Automotive doesn’t rely on a single test when diagnosing every air conditioning problem.

The system appeared acceptable during the vacuum test.

The nitrogen pressure test told us something different.

Pressure and vacuum place different forces on seals and components within the air conditioning system. Some faults may become more noticeable under positive pressure.

Using several diagnostic methods can give us a clearer picture of the system’s condition.

This approach helps us find the actual fault before recommending repairs.

Why We Don’t Just Regas a Leaking Aircon System

Simply adding R134a refrigerant would not repair a leak behind the dashboard.

The air conditioning might begin cooling again after a regas. However, refrigerant could escape again through the existing leak.

The customer would eventually return to the same problem.

This is why CMM Automotive focuses on car air conditioning diagnosis in Perth before recommending a regas or repair.

We want to understand why the system stopped cooling.

Mobile Car Air Conditioning in Balga

CMM Automotive provides mobile air conditioning diagnosis throughout Balga and the Perth metropolitan area.

We bring professional air conditioning equipment directly to your home or workplace.

Our services include performance testing, leak detection, vacuum testing and nitrogen pressure testing. We also diagnose compressor and other air conditioning faults.

Where possible, we identify the cause before recommending repairs.

This can prevent unnecessary parts replacement and repeated regassing.

Car Air Conditioning Not Working?

If your vehicle’s air conditioning has stopped cooling, the system may need more than a simple regas.

A refrigerant leak can occur in several different areas of the system. Some leaks can remain hidden behind the dashboard.

CMM Automotive provides Mobile Car Air Conditioning Perth services for many common air conditioning problems.

We can test the system, explain what we find and recommend the appropriate next step.

Frequently Asked Questions

Can a car aircon system pass a vacuum test and still leak?

Yes. Some leaks may behave differently under vacuum and positive pressure. Further testing can help locate difficult air conditioning leaks.

Why would refrigerant appear at the dashboard vents?

A leak within the HVAC housing can allow traces of refrigerant into the airflow. The blower may then carry those traces through the vents.

Why does CMM Automotive use nitrogen pressure testing?

Nitrogen pressure testing can help locate leaks without unnecessarily adding refrigerant to a faulty system.

Does CMM Automotive provide mobile aircon diagnosis in Balga?

Yes. CMM Automotive provides mobile car air conditioning diagnosis and repairs throughout Balga and the Perth metropolitan area

Mobile Car Air Conditioning Perth recently helped a Hyundai i30 owner whose air conditioning was blowing warm air from every vent. The system was no longer providing the cold air needed for comfortable driving.

CMM Automotive attended the vehicle and carried out a series of air conditioning tests. We first pressure tested the system with nitrogen and found no obvious leaks.

However, further testing told a different story.

The system would not hold a vacuum. Our diagnosis eventually identified a leaking main seal inside the air conditioning compressor. We replaced the faulty compressor to repair the system correctly.

Hyundai i30 Air Conditioning Blowing Warm Air

Warm air from the vents is one of the most common signs of a car air conditioning problem.

Many drivers immediately assume that the system simply needs more refrigerant. However, low refrigerant often indicates another problem.

A leak may allow refrigerant to escape from the system. Other faults can also prevent the air conditioning from cooling correctly.

For this reason, CMM Automotive focuses on diagnosis before recommending repairs.

Simply adding refrigerant without finding the cause may only provide a temporary result.

Nitrogen Pressure Testing the Air Conditioning System

We started our diagnosis by pressure testing the Hyundai’s air conditioning system with nitrogen.

Nitrogen pressure testing can help locate refrigerant leaks. The test allows us to pressurise the system without unnecessarily releasing refrigerant into the atmosphere.

In this case, the system passed the initial nitrogen pressure test. We could not detect an obvious leak during this stage.

However, that did not mean the system was fault-free.

Further testing was required.

The Air Conditioning System Would Not Hold Vacuum

The next step involved vacuum testing the air conditioning system.

A healthy sealed system should maintain the required vacuum during testing. The Hyundai i30 failed this test.

The system would not hold vacuum.

This result gave us another important clue. We continued investigating the system rather than simply regassing the vehicle.

Further diagnosis identified the air conditioning compressor as the source of the problem.

Leaking Air Conditioning Compressor Seal

The main seal inside the Hyundai’s air conditioning compressor was leaking.

This fault explained why the system could behave differently during the nitrogen pressure test and the vacuum test.

Pressure and vacuum place seals under different conditions. A seal may appear to hold under positive pressure but leak when the system operates under vacuum.

This is why using more than one diagnostic method can be important.

If we had relied only on the initial nitrogen test, we could have missed the compressor seal problem.

Replacing the Hyundai i30 Air Conditioning Compressor

Once we identified the leaking compressor seal, we could recommend the correct repair.

CMM Automotive replaced the faulty air conditioning compressor.

Replacing the compressor addressed the actual cause rather than simply treating the warm air symptom.

This Hyundai i30 is a good example of why professional car air conditioning diagnosis in Perth matters.

Air conditioning systems contain several components that must work together correctly. Guessing at the fault can lead to unnecessary parts replacement or repeated regassing.

Testing allows us to make a more informed repair decision.

Why We Don’t Simply Regas Every Warm Aircon System

A regas isn’t automatically the answer when your car’s air conditioning starts blowing warm air.

If refrigerant has escaped, we need to consider why it escaped.

Air conditioning leaks can occur in hoses, condensers, evaporators and seals. Compressors can also develop leaks as they age.

Adding refrigerant to a leaking system doesn’t repair the leak.

The system may cool temporarily before losing refrigerant again.

CMM Automotive tests and diagnoses the system before recommending the most appropriate repair.

Frequently Asked Questions

Why is my Hyundai i30 air conditioning blowing warm air?

Several problems can cause warm air. These include low refrigerant, leaks, compressor faults and other air conditioning system problems.

Can an aircon system pass a nitrogen test but fail a vacuum test?

Yes. Some seals can behave differently under pressure and vacuum. Using different testing methods can help identify difficult leaks.

Does warm air always mean my car needs an aircon regas?

No. The system may have a leak or another fault. Diagnosis should identify the cause before adding refrigerant.

Yes. CMM Automotive provides mobile car air conditioning diagnosis and repairs throughout the Perth metropolitan area.

Mobile Roadside Assistance Perth recently helped a gentleman in Guildford after his Ford suddenly refused to select a gear. The engine would run, but the transmission could not engage the selected gear correctly.

The customer contacted CMM Automotive for roadside assistance. We travelled directly to the Ford in Guildford and inspected the gear selection problem.

Our inspection found an issue with the transmission linkage. We temporarily secured the linkage to the transmission at the roadside. This allowed the customer to drive the vehicle again and arrange a permanent repair.

Why Would a Ford Suddenly Not Select Gear?

A vehicle that suddenly won’t select a gear can have several possible faults.

Drivers may immediately suspect an internal transmission failure. However, the transmission itself isn’t always the cause.

The gear selector uses a linkage or cable system to transfer the driver’s selection to the transmission. A problem with this system can prevent the transmission from selecting the requested gear.

The driver may move the gear selector, but the transmission may not respond correctly.

This is why diagnosing the problem before assuming the worst can save time and unnecessary expense.

Roadside Transmission Problem in Guildford

CMM Automotive attended the Ford at the customer’s location in Guildford.

We inspected the gear selection system and identified a problem with the transmission linkage. The fault prevented the driver from selecting the required gear correctly.

Rather than immediately arranging a tow truck, we assessed whether we could safely provide a temporary roadside solution.

We temporarily attached the transmission linkage back to the transmission. This restored gear selection and allowed the Ford to drive again.

The temporary measure helped the customer get the vehicle moving. However, the linkage still required a proper permanent repair.

Temporary Roadside Repairs Can Get You Moving

Not every roadside repair provides a permanent solution.

Sometimes a mobile mechanic can safely carry out a temporary repair that allows the driver to move the vehicle. The customer can then arrange the correct repair without requiring an immediate tow.

Safety always comes first.

A temporary repair must suit the fault and the condition of the vehicle. Some breakdowns require towing because driving the vehicle could cause further damage or create a safety risk.

In this case, temporarily securing the Ford’s transmission linkage allowed the vehicle to select gear again.

Does a Gear Selection Problem Mean the Transmission Has Failed?

Not necessarily.

Automatic transmissions contain many mechanical, hydraulic and electronic components. A fault with any of these systems can cause gear selection problems.

However, external components can also cause similar symptoms.

A damaged or disconnected selector linkage may prevent the transmission from receiving the driver’s gear selection. The transmission may still function correctly once the linkage operates as intended.

Proper diagnosis can help identify the actual cause before anyone considers major transmission repairs.

What Should You Do If Your Car Won’t Select Gear?

Don’t force the gear selector if your vehicle suddenly refuses to select a gear.

Forcing the selector may damage other components and make the original problem worse.

Instead, move the vehicle to a safe location if possible. If you can’t safely move it, contact roadside assistance.

An experienced mobile mechanic can inspect the vehicle and determine whether a roadside solution is possible.

This Ford callout shows how mobile roadside assistance in Perth can help with more than batteries, tyres and starting problems.

Mechanical faults can also leave a perfectly running engine unable to move the vehicle.

We attend many different roadside problems. These include flat batteries, starting faults, flat tyres and unexpected mechanical issues.

We can also investigate many faults directly at the vehicle’s location.

Our goal is to identify the cause and find a practical solution wherever possible.

If the vehicle requires further repairs, we’ll explain the problem and discuss the next step.

Car Won’t Select Gear in Perth?

A vehicle that starts but won’t select gear can leave you stranded without warning.

The problem doesn’t automatically mean that the transmission has suffered a major internal failure. A linkage, cable or another external component may cause the fault.

CMM Automotive provides Mobile Roadside Assistance Perth and can come directly to your location.

Professional roadside diagnosis can identify the problem and determine whether we can get your vehicle moving again.

Frequently Asked Questions

Why won’t my automatic car select a gear?

Mobile Roadside Assistance Perth recently helped a lady in Morley after the fan belt on her vehicle snapped. The breakdown left her unable to continue her journey and in need of roadside help.

CMM Automotive travelled directly to the vehicle in Morley to inspect the problem. We found that the drive belt had snapped. The condition of the belt also highlighted why regular vehicle servicing and maintenance are so important.

A worn belt can often show warning signs before it finally fails.

What Happens When a Fan Belt Snaps?

Many drivers still use the term “fan belt” to describe the engine’s accessory drive belt. Depending on the vehicle, this belt can operate several important components.

These may include the alternator, air conditioning compressor and power steering pump. On some engines, the belt may also drive the water pump.

When the belt snaps, these components can immediately stop working.

The battery warning light may appear because the alternator has stopped charging. Steering may suddenly become much heavier on some vehicles. If the belt drives the water pump, the engine may also begin to overheat.

For these reasons, you should take a broken drive belt seriously.

Roadside Assistance in Morley

The lady contacted CMM Automotive after her vehicle broke down in Morley.

We came directly to her location and inspected the vehicle. We quickly identified the snapped belt as the cause of the immediate problem.

This type of breakdown shows the value of mobile roadside assistance in Perth. An experienced mobile mechanic can inspect the vehicle where the problem occurs.

The driver can then understand what has gone wrong before deciding on the next step.

Can Poor Servicing Lead to Belt Failure?

Regular servicing gives a mechanic an opportunity to inspect belts and other important engine components.

Drive belts naturally deteriorate as they age. Heat, kilometres and constant movement can eventually cause the rubber to harden or crack.

A belt may develop visible cracks, frayed edges or other signs of wear.

Regular inspections can identify many of these warning signs before the belt snaps. A mechanic can then recommend replacement before the vehicle breaks down.

Skipping regular servicing may allow worn components to remain unnoticed for longer.

In this case, the snapped belt provided another reminder of why preventative maintenance matters.

Signs Your Fan Belt May Need Attention

A drive belt doesn’t always fail without warning.

You may hear a squealing or chirping noise from the engine bay. The belt may also show visible cracking or fraying.

A battery warning light can sometimes indicate a belt or charging system problem. Heavy steering may also occur if the belt stops driving a hydraulic power steering pump.

Never ignore an unusual noise from the belt area.

Having the vehicle inspected early may prevent a roadside breakdown later.

Should You Keep Driving With a Broken Fan Belt?

No. If the drive belt has snapped, stop the vehicle in a safe location.

Continuing to drive may create additional problems. This becomes especially important if the belt operates the water pump.

Without coolant circulation, the engine temperature can rise quickly. Severe overheating can cause expensive engine damage.

The alternator may also stop charging the battery after the belt breaks. Eventually, the battery will lose enough power for the engine to stop.

Calling roadside assistance allows a mechanic to assess the situation before you risk further damage.

Regular Servicing Can Prevent Breakdowns

Not every breakdown is preventable. However, regular maintenance can reduce the chance of many common problems.

A vehicle service involves more than changing the engine oil and filter. It also gives a mechanic the chance to inspect components that wear with age and kilometres.

Belts, hoses, fluids, tyres and batteries all deserve regular attention.

Finding a worn component during a service is much better than discovering it after your vehicle stops on the side of the road.

Mobile Roadside Assistance Perth recently helped a customer with a Holden in South Perth after the vehicle suffered a flat tyre. A flat tyre can happen without warning and quickly bring your journey to a stop.

Changing a tyre may sound like a simple job. However, it isn’t always easy or safe to do at the roadside. The driver contacted CMM Automotive for assistance, and we travelled directly to the vehicle in South Perth.

Flat Tyre Assistance in South Perth

A flat tyre can occur for many reasons. A nail or screw may puncture the tyre while driving. Damage from a pothole or road debris can also cause a sudden loss of pressure.

Sometimes a tyre loses air slowly over several days. The driver may only notice the problem when the tyre becomes completely flat.

Whatever the cause, driving on a flat tyre can quickly damage it. It can also damage the wheel and affect the driver’s control of the vehicle.

The safest option is to stop in a suitable location as soon as you notice the problem.

CMM Automotive Attends the Holden

For this roadside callout, CMM Automotive attended the Holden at its location in South Perth.

The customer needed help getting the vehicle mobile again. We came directly to the vehicle, which saved the driver from trying to deal with the flat tyre alone.

This type of callout is a good example of how roadside assistance can help with everyday vehicle problems.

Not every roadside breakdown involves an engine or electrical fault. Sometimes something as simple as a flat tyre can leave a vehicle unable to continue its journey.

Should You Drive on a Flat Tyre?

You should avoid driving any significant distance on a flat tyre.

A tyre relies on air pressure to support the weight of the vehicle. When the tyre loses its pressure, the sidewall can become trapped between the road and the wheel.

Driving in this condition can cause serious tyre damage.

Even a short journey may turn a repairable puncture into a tyre that needs replacement. Continuing to drive may also damage the wheel.

If you notice a flat tyre, find a safe place to stop. Roadside assistance can then help you decide on the next step.

Why Changing a Tyre Isn’t Always Simple

Many drivers have changed a spare tyre before. However, several problems can make the job difficult.

Wheel nuts may be extremely tight. The vehicle’s jack may also be difficult to use, damaged or missing.

Some vehicles don’t even carry a conventional spare wheel.

Roadside conditions can create another problem. Changing a tyre beside moving traffic can put the driver in a dangerous position.

If you don’t feel confident changing the wheel, calling for assistance is often the better choice.

More Than Just Flat Battery Assistance

People often associate roadside assistance with flat batteries and jump starts. In reality, drivers can experience many different problems while travelling.

A flat tyre is one of them.

This Holden callout shows how mobile roadside assistance in Perth can help with unexpected problems that prevent a vehicle from continuing its journey.

CMM Automotive can come directly to your location and assess the situation. We aim to provide a practical solution wherever possible.

Frequently Asked Questions

Can I drive a short distance with a flat tyre?

It is best to avoid driving on a flat tyre. Driving can damage the tyre and may also damage the wheel.

Can roadside assistance help with a flat tyre?

Yes. Roadside assistance can help when a flat tyre prevents you from safely continuing your journey.

Does CMM Automotive provide roadside assistance in South Perth?

Yes. CMM Automotive provides mobile roadside assistance in South Perth and throughout the Perth metropolitan area.

Mobile Roadside Assistance Perth recently helped a lady in Greenwood whose Subaru would turn over but would not start. The starter motor was cranking the engine normally. However, the engine would not fire and run.

A car that cranks but refuses to start can have several possible causes. Instead of guessing or replacing parts, the customer contacted CMM Automotive for help.

We travelled to Greenwood to inspect the Subaru and diagnose the problem at the vehicle’s location.

Why Does a Car Turn Over But Not Start?

When you turn the key and hear the engine cranking, the starter motor is doing its job. However, the engine still needs several things before it can run.

The engine needs the correct fuel supply, ignition and air. Modern vehicles also rely on sensors and electronic systems to control the engine.

A fault in any of these areas can prevent the engine from starting.

Possible causes include a fuel supply problem, ignition fault or failed sensor. An electrical problem can also stop the engine from starting.

This is why proper diagnosis matters.

Subaru Won’t Start in Greenwood

When a vehicle won’t start, it can leave the owner in a difficult situation. The car may be sitting at home, at work or in a car park.

In this case, the Subaru was located in Greenwood.

CMM Automotive came directly to the vehicle. This allowed us to begin checking the problem without the owner arranging a tow to a workshop.

A mobile mechanic can often carry out important diagnostic tests where the vehicle has broken down.

A Flat Battery Isn’t Always the Problem

Many people immediately suspect the battery when their car won’t start. However, a battery problem usually affects how quickly the engine cranks.

In this Subaru, the engine was turning over but refusing to start.

That distinction is important.

A strong cranking engine tells a mechanic something different from a vehicle that only clicks when you turn the key.

We can then focus our diagnosis on the systems that allow the engine to start and run.

Diagnosing a Car That Cranks But Won’t Start

Finding the cause requires a logical approach.

We first look at what the vehicle is doing when the driver attempts to start it. We can then check the systems most likely to cause the problem.

Modern diagnostic equipment can also provide valuable information. Fault codes and live vehicle data may help identify an electrical or engine management problem.

However, a fault code doesn’t always mean that a particular component needs replacement. Further testing helps us determine what is actually causing the starting problem.

This approach can reduce unnecessary repairs and parts replacement.

Mobile Roadside Assistance Can Save a Tow

A vehicle that turns over but won’t start doesn’t always need immediate towing.

Mobile diagnosis may identify a problem that we can address at the vehicle’s location. Even when a roadside repair isn’t possible, diagnosis can still provide useful information.

Knowing what has failed can help the owner decide on the next step.

This Subaru callout shows why mobile roadside assistance in Perth can be useful when a vehicle unexpectedly refuses to start.

Instead of guessing at the problem, CMM Automotive can come directly to the vehicle and investigate the cause.

Frequently Asked Questions

Why does my car turn over but not start?

Several faults can cause this problem. Common causes include fuel supply problems, ignition faults, electrical issues and faulty engine sensors.

Does a car that cranks but won’t start need a new battery?

Not necessarily. If the engine cranks strongly, another fault may prevent it from starting. Proper testing can identify the cause.

Can CMM Automotive diagnose a no-start problem at my location?

Yes. CMM Automotive provides mobile roadside diagnosis across Perth for many common starting and breakdown problems.

Mobile Roadside Assistance Perth can help with much more than a flat battery or a vehicle that won’t start. “Recently, a gentleman contacted CMM Automotive after accidentally adding too much engine oil to his Toyota LandCruiser.” Soon afterwards, the LandCruiser began producing smoke from the exhaust, leaving the owner concerned that something was seriously wrong.

The customer contacted CMM Automotive and asked us to come to his location, inspect the vehicle and remove the excess engine oil.

What Happens When You Put Too Much Oil in an Engine?

Engine oil is essential for protecting the internal components of an engine. However, having too much oil can also cause problems.

Every engine has a specified oil capacity. When the oil level rises significantly above the maximum mark on the dipstick, the rotating components inside the engine can come into contact with the excess oil. This can cause the oil to become aerated or create excessive oil mist inside the engine.

“Excess oil may travel through the engine’s ventilation system and enter the intake. The engine may then burn the excess oil.” One possible symptom is smoke coming from the exhaust.

Seeing a Toyota LandCruiser suddenly smoking after adding engine oil can understandably be alarming.

Roadside Diagnosis of the Toyota LandCruiser

When CMM Automotive attended the vehicle, we were able to assess the situation at the customer’s location.

“The problem appeared soon after the owner added more engine oil. We checked the dipstick and found the oil level well above the correct range.”

The owner stopped driving the LandCruiser and contacted CMM Automotive for professional assistance.”

“This Toyota LandCruiser callout shows that mobile roadside assistance in Perth covers more than jump starts and flat batteries.”

Removing the Excess Engine Oil

“We drained the excess oil from the Toyota LandCruiser. We then checked the oil level and made sure it was correct.”

“This Toyota LandCruiser callout shows that mobile roadside assistance in Perth covers more than flat batteries and jump starts.”

Sometimes a vehicle may still start and drive, but a mechanical problem makes continuing the journey a bad idea. “Having a mobile mechanic come directly to the vehicle allows us to assess the problem before the owner risks causing further issues.”

Why You Shouldn’t Ignore an Overfilled Engine

If you discover that you have overfilled your engine with oil, don’t assume that more oil means better lubrication.

The correct oil level is important.

“If the oil level is well above the maximum mark, avoid driving the vehicle. This is especially important if the engine starts smoking or running differently.”

Some drivers may be tempted to keep driving and wait for the excess oil to burn away. That isn’t a good approach because you don’t know exactly how much excess oil is in the engine or what effect it may be having.

Removing the excess oil and returning the level to the manufacturer’s recommended range is the safer option.

Frequently Asked Questions

Can too much engine oil cause exhaust smoke?

Yes. Excess engine oil can sometimes enter areas where it is burned by the engine, which may result in smoke from the exhaust.

Can I drive if I have overfilled my engine oil?

If the oil level is significantly above the maximum mark, particularly if the engine is smoking or behaving abnormally, it is better to have the vehicle inspected and the oil level corrected before continuing to drive.

Can CMM Automotive come to my location?

Yes. CMM Automotive provides mobile roadside assistance throughout the Perth metropolitan area.

A Ford Fiesta vehicle inspection Perth recently completed by CMM Automotive in The Vines uncovered several mechanical, electrical and safety concerns. Our inspection identified ECU fault codes, a possible engine oil pressure switch problem, poor front tyres, deteriorated front brake rotors and several other issues.

A professional pre-purchase inspection can reveal problems that a buyer may not notice during a quick look or short test drive. Finding these issues before purchasing a used vehicle can also help the buyer understand potential repair and maintenance costs.

Ford Fiesta Interior Inspection

We started the inspection by checking the vehicle’s interior, controls and electrical equipment.

The driver’s floor carpet had holes and showed signs of wear. We also noticed that the interior rear-view mirror was loose and required attention.

During our initial checks, the left-hand front electric window did not operate. Interestingly, the window began working later in the inspection. An intermittent electrical problem like this may require further investigation to determine the cause.

ECU Fault Codes Found

Diagnostic scanning formed an important part of this Ford Fiesta vehicle inspection Perth.

Several fault codes were present in the ECU. These included a fault relating to incorrect camshaft and crankshaft correlation, along with an intake camshaft sensor fault.

Camshaft and crankshaft correlation faults deserve further investigation because several mechanical or electrical problems can potentially trigger them.

The engine oil warning light also remained illuminated. Our inspection indicated that the engine oil pressure switch may have a fault. Further testing would help confirm the exact cause before replacing any components.

Engine Bay and Battery Inspection

The battery performed poorly during testing and may require replacement.

We also checked the general condition of the engine bay and surrounding components. During these checks, we noticed that the bonnet stay was not positioned correctly.

Small problems may appear insignificant individually. However, documenting them helps provide the prospective buyer with a more complete assessment of the vehicle.

Front Tyres and Brake Rotors

Our steering, brake and suspension inspection identified further items requiring attention.

Both front tyres required replacement. Tyre condition plays an important role in vehicle safety, handling and braking performance, making this an important consideration when purchasing a used car.

The front brake disc rotors also had considerable marking and rust across their surfaces. Brake repairs and tyre replacement can add to the immediate costs of purchasing a vehicle, so identifying their condition beforehand gives the buyer useful information.

Ford Fiesta Body and Exterior Condition

Several exterior problems were also present.

Damage to the front of the vehicle had smashed the fog light. Both headlights appeared cloudy and would benefit from attention to improve their condition.

We also noticed deterioration in the paint finish around the spoiler, with areas of the clear coating beginning to fail.

Although cosmetic problems may not affect the mechanical operation of a vehicle, they remain important when assessing its overall condition and value.

Ford Fiesta Road Test

A road test provides an opportunity to assess how a vehicle performs under normal driving conditions.

During the road test, the engine warning light remained illuminated. Combined with the ECU fault codes identified during our diagnostic scan, this was an important finding that required further investigation.

We also noticed excessive noise from the exhaust system. The source of the exhaust noise would require further inspection to determine what repairs the vehicle needs.

Why a Pre-Purchase Inspection Matters

This Ford Fiesta vehicle inspection Perth highlights why buyers should consider a professional inspection before purchasing a used vehicle.

Our inspection identified ECU fault codes, an illuminated engine warning light, a possible oil pressure switch fault, poor battery condition, two front tyres requiring replacement and deteriorated front brake rotors. We also found several electrical, interior and exterior concerns.

CMM Automotive provides mobile pre-purchase vehicle inspections across Perth, including The Vines and surrounding suburbs. We inspect vehicles at their location and provide an independent assessment to help customers make a more informed purchasing decision.

Yes. A pre-purchase inspection can identify mechanical, electrical, braking, tyre and body concerns that may not be obvious during a short test drive.

Can a vehicle inspection find ECU fault codes?

Yes. Diagnostic scanning can identify stored ECU fault codes and provide valuable information about faults that may require further investigation.

Does CMM Automotive inspect vehicles in The Vines?

Yes. CMM Automotive provides mobile pre-purchase vehicle inspections in The Vines and throughout many areas of Perth.

A Nissan Navara vehicle inspection Perth recently completed by CMM Automotive in Ocean Reef identified several mechanical, safety and maintenance issues. The inspection included the vehicle interior, engine bay, steering, brakes, suspension, body panels and a road test.

Buying a used 4WD or ute can involve significant repair costs if existing problems aren’t identified before the purchase. A professional pre-purchase inspection can help uncover these problems and provide a clearer picture of the vehicle’s overall condition.

Nissan Navara Interior Inspection

We started by checking the interior and general condition of the Navara.

The carpets were dirty, while several door trims had scratches.Further checks revealed a loose glove box and interior lights that did not operate.

We found damage to the vehicle’s antenna. We also found damage to both ignition keys, which needed attention.

While some of these items are relatively minor, they can provide useful information about how previous owners maintained and treated the vehicle.

Engine Oil Leaks Identified

The engine bay inspection revealed several areas requiring further attention.

Firstly, the battery tested poorly and may require replacement.

More importantly, we identified an engine oil leak around the turbo. An additional engine oil leak was found around the rear main seal area. Engine oil was also present on the oil filter.

Oil leaks can vary considerably in severity and repair cost. Identifying their location during a Nissan Navara vehicle inspection Perth gives the potential buyer an opportunity to investigate repair costs before purchasing the vehicle.

Front Suspension, Tyres and Brakes

Several concerns were identified around the front suspension and braking system.

The front struts appeared very old, while the front tyres had developed a lumpy or uneven condition.

The front brake pads had approximately 45% remaining at the time of our inspection.

Although the remaining brake pad material was reasonable, the road test revealed another braking issue. The front brakes produced a noticeable shudder under braking.

Brake shudder can have several possible causes, so further inspection would be required to confirm exactly what repairs are needed.

Rear Suspension, Tyres and Brakes

The rear of the vehicle also required attention.

The rear tyres required replacement, while the rear brake shoes were getting low. We also noted that the rear shock absorbers showed considerable signs of age.

Tyres, brakes, shock absorbers and struts can represent a considerable expense when several components require attention at the same time. These are important costs to consider when assessing the true value of a used vehicle.

Navara Body and Panel Condition

The front bumper had minor scratches and dents. We also found stone chips on the left-hand front guard.

At the rear, the bumper was dented and the tailgate was not opening correctly.

Although cosmetic damage may not prevent a vehicle from being driven, we document these issues so the customer has a better understanding of its overall condition.

Nissan Navara Road Test

The road test is an important part of our mobile pre-purchase vehicle inspections in Perth.

During this road test, the Nissan Navara did not feel particularly comfortable. The vehicle felt slightly rough during testing, and the front brakes produced a noticeable shudder.

Combined with the aged suspension components and tyre condition identified during the physical inspection, these findings were important information for the prospective buyer.

Pre-Purchase Vehicle Inspections Across Perth

This Nissan Navara vehicle inspection Perth demonstrates how several individual problems can quickly add up when purchasing a used vehicle.

The inspection identified engine oil leaks, a poor battery, aged suspension components, tyres requiring attention, low rear brake shoes, brake shudder and several body and interior issues.

CMM Automotive provides mobile pre-purchase vehicle inspections across Perth, including Ocean Reef and surrounding suburbs. We inspect the vehicle at its location and provide an independent assessment of its condition before you make your purchasing decision.

Can a pre-purchase inspection identify oil leaks?

Yes. We inspect the engine bay and surrounding components for visible signs of oil and fluid leaks.

Does CMM Automotive inspect vehicles in Ocean Reef?

Yes. CMM Automotive provides mobile pre-purchase vehicle inspections in Ocean Reef and throughout many areas of Perth.

A Subaru Outback vehicle inspection Perth recently carried out by CMM Automotive in Wanneroo identified several mechanical, electrical and safety-related problems. Some of these faults may not have been immediately obvious to someone inspecting the vehicle without professional equipment.

A pre-purchase inspection can provide valuable information about a vehicle’s condition before you commit to buying it. This Subaru Outback is a good example of why checking more than the vehicle’s external appearance is important.

Subaru Outback Diagnostic Scan

As part of the vehicle inspection, we carried out an electronic diagnostic scan. Several ECU fault codes were present:

• P1603 – Engine Stall
• P1604 – Stability Malfunction
• C1935 – Ignition Switch Circuit
• B14A5 – Refrigeration Flow Sensor Invalid

Fault codes can provide important information about previous or current problems within a vehicle.

However, a fault code doesn’t always confirm that a particular component requires replacement. Further diagnosis may be necessary to determine the cause of the fault.

The presence of several codes was therefore an important finding during this Subaru Outback vehicle inspection Perth.

Interior and Electrical Inspection

Several other problems were identified during the inspection.

The windscreen wiper blades were in very poor condition and were hanging off. Wipers are an important safety item and should provide the driver with clear visibility during wet weather.

We also found that the vehicle’s side camera was not operating correctly.

The left-hand rear door lock was another item requiring attention, as it was not working during our inspection.

Engine Bay Inspection

Our engine bay inspection identified two areas requiring attention.

The battery tested low and may require replacement. A weak battery can potentially cause starting problems and other electrical issues, particularly as its condition continues to deteriorate.

We also identified an oil leak from the power steering pump. Oil leaks should be investigated before they become more severe or cause additional problems.

Finding issues like these before purchasing a vehicle gives the buyer an opportunity to consider potential repair costs.

Rear Brakes and Disc Rotors Worn

The braking system was another significant finding during this Subaru Outback vehicle inspection Perth.

The rear brake pads were worn out and required attention. The rear brake disc rotors were also worn and required replacement.

Brake condition is an important part of any pre-purchase vehicle inspection because repairs can add considerably to the cost of purchasing a used vehicle.

Identifying worn brakes before buying allows the customer to factor these repairs into their purchasing decision.

Body and Exterior Condition

The vehicle also had some visible cosmetic damage.

We noted scratching on the front bumper during the inspection. While cosmetic damage may not affect how the vehicle drives, documenting it helps provide the buyer with a more complete picture of the vehicle’s overall condition.

Subaru Outback Road Test

A road test can reveal problems that aren’t always noticeable while a vehicle remains stationary.

During the road test, we found that this Subaru Outback pulled to the left.

A vehicle pulling to one side can have several possible causes. These may include wheel alignment, tyre condition, suspension components or other steering-related issues. Further investigation would be required to determine the exact cause.

Why a Pre-Purchase Vehicle Inspection Matters

This Subaru Outback demonstrates why a professional inspection can be valuable before buying a used vehicle.

Although some problems were relatively minor, the inspection also identified worn rear brakes and rotors, a leaking power steering pump, a weak battery, several ECU fault codes and an issue during the road test.

At CMM Automotive, we provide mobile pre-purchase vehicle inspections across Perth. We inspect the vehicle at its location and provide an independent assessment to help you make a more informed purchasing decision.

When your car air conditioning stops blowing cold air, it’s easy to assume the system simply needs a regas. In reality, poor cooling performance can have many different causes. Without a professional car air conditioning system diagnosis, replacing parts or adding more refrigerant may only provide a temporary solution while the real problem remains.

At CMM Automotive, every mobile car air conditioning repair begins with a thorough diagnosis. We believe it’s important to identify the source of the fault before recommending repairs. This approach helps our customers avoid unnecessary costs while ensuring the correct repair is carried out the first time.

Why Diagnosis Comes Before Repairs

Modern vehicle air conditioning systems are made up of several components that work together to keep the cabin cool. If just one component fails, the entire system may stop operating correctly.

Common causes of poor air conditioning performance include:

• Refrigerant leaks.
• Worn compressors.
• Faulty condensers.
• Leaking evaporators.
• Damaged hoses or pipework.
• Electrical faults.
• Cooling fan problems.
• Pressure switch failures.

Although many of these faults produce similar symptoms, they require completely different repairs. That’s why professional diagnosis is so important.

Professional Car Air Conditioning Diagnosis

At CMM Automotive, we use professional testing equipment to determine why your air conditioning system has stopped cooling.

Depending on the symptoms, our diagnosis may include:

• Recovering the remaining refrigerant.
• Nitrogen pressure testing for refrigerant leaks.
• Visual inspection of air conditioning components.
• Operating pressure checks.
• Vent temperature testing.
• Compressor performance checks.
• Electrical system testing.
• Charging system inspection where required.

By completing these tests, we can identify the cause of the problem before recommending repairs.

Why a Regas Isn’t Always the Answer

One of the biggest misconceptions is that every air conditioning fault requires a regas.

If the system has lost refrigerant because of a leak, adding more refrigerant without repairing the fault will usually result in the system losing its cooling performance again. This can lead to repeated regassing, unnecessary expense and continued frustration.

Professional car air conditioning leak detection allows us to locate the source of the refrigerant loss before recommending the most appropriate repair.

Saving You Time and Money

Professional diagnosis often saves money in the long run.

Rather than replacing parts based on guesswork, we identify the fault first and explain our findings clearly. This allows you to understand the condition of your vehicle and decide on the most appropriate repair.

Our goal is simple — diagnose the fault first, recommend the correct repair second.

Choose CMM Automotive for Mobile Car Air Conditioning Diagnosis

Professional diagnosis gives you confidence that you’re repairing the actual fault—not simply treating the symptoms.

Used Hyundai Elantra inspection Perth is one of the smartest investments you can make before buying a second-hand vehicle. Although the Hyundai Elantra has earned a reputation for reliability and affordability, buyers should never assume every used example is free from costly mechanical or safety issues.. During our inspection of this 2009 Hyundai Elantra in Northbridge, we uncovered several faults that every potential buyer should consider before signing the paperwork.

At CMM Automotive, our mobile inspections give buyers an independent assessment of a vehicle’s condition before they commit to buying. We inspect the interior, engine bay, steering, brakes, suspension, bodywork and road performance so you understand exactly what you’re buying.

Interior Condition and Safety Equipment

The interior of this Hyundai Elantra showed the normal signs of use you would expect from a vehicle of its age, but several items require attention.

Minor scuff marks were present on the door trims, and the roof lining had visible marks that affected the overall presentation of the vehicle.

Replace the front wiper blades to maintain clear visibility during wet weather.

The cigarette lighter socket was not working, which may inconvenience drivers who use phone chargers, GPS units or other 12-volt accessories.

More importantly, we found that the left-hand front door lock was faulty, and the centre rear seatbelt would not retract correctly. We recommend repairing the seatbelt immediately because it may not provide the intended protection during an accident.

The remote locking system also failed to operate the left-hand front door, which appears to be related to the faulty door lock mechanism.

Engine Bay Inspection

The engine bay revealed several mechanical issues that buyers should budget to repair.

Battery testing showed the battery was below specification and nearing the end of its service life. A weak battery can lead to unreliable starting and unexpected breakdowns, particularly during colder weather.

The most significant fault was a leaking water pump.

Water pumps are a critical part of the cooling system, circulating coolant through the engine to control operating temperature. Repair the leaking water pump promptly because continued coolant loss can cause the engine to overheat, leading to major engine damage and expensive repairs.

We also found cracks and splits in the air conditioning belt and the remaining accessory drive belts.

We recommend replacing worn belts before they fail because doing so helps prevent breakdowns and expensive repairs.

Steering, Brakes and Suspension

Our inspection found that the front brake pads had worn beyond their serviceable limit and now require replacement.

Safe braking performance depends on good-quality brake components, so we recommend replacing the front brake pads before driving the vehicle regularly.

We also found excessive inner edge wear on the front tyres.

This type of tyre wear commonly indicates incorrect wheel alignment, worn suspension components or steering geometry issues. Simply replacing the tyres without correcting the underlying cause may result in the new tyres wearing unevenly as well.

TThe rear brakes appear relatively new, and our inspection found them in good condition.

Chassis and Body Inspection

The body presented reasonably well overall, although several cosmetic issues were identified.

The front bumper had minor scuff marks, including additional scuffing on the inner section of the bumper.

The headlight lenses had started to fade, reducing the vehicle’s appearance and potentially affecting night-time visibility.

We recommend replacing the bald spare tyre before you need it in an emergency.

We also found several minor dents on the roof, together with general cosmetic wear that is consistent with the vehicle’s age.

Road Test Results

During our road test, the Hyundai Elantra consistently pulled to the right while driving.

A vehicle that pulls to one side should always be investigated. Common causes include incorrect wheel alignment, uneven tyre wear, tyre pressure differences or worn steering and suspension components.

Because we also found significant inner edge wear on the front tyres, we recommend carrying out a complete wheel alignment and suspension inspection before purchasing the vehicle.

Overall Assessment

Our used Hyundai Elantra inspection Perth uncovered several issues that should be considered before buying this vehicle.

The leaking water pump represents the highest repair priority because cooling system failures can quickly become expensive if left unattended. The poor battery, cracked drive belts, worn front brake pads, faulty door locking system and excessive front tyre wear will also require attention.

Although many of the remaining faults are cosmetic, they still contribute to the overall cost of bringing the vehicle up to a good standard.

A professional used Hyundai Elantra inspection Perth provides buyers with independent information that can help negotiate a better purchase price, budget for future repairs and avoid unexpected surprises after taking ownership.

Before purchasing any used vehicle, we recommend arranging a professional inspection to help identify hidden faults, avoid unexpected repair costs and make an informed buying decision.To book a inspection press HERE

What causes inner edge tyre wear?

Inner edge tyre wear is commonly caused by poor wheel alignment, worn suspension components or steering issues. A professional inspection helps identify the underlying cause.

Is a weak battery worth replacing before selling a car?

Yes. Replacing a weak battery improves reliability and can prevent starting problems for the next owner.

Why is a vehicle pulling to the right?

A pull to one side can result from wheel alignment issues, uneven tyre wear, incorrect tyre pressures or worn steering and suspension components. The cause should always be diagnosed before purchase.

Why have a professional used car inspection before buying?

A professional inspection identifies mechanical, safety and cosmetic issues that are easy to overlook during a private inspection. It gives buyers confidence, helps with price negotiations and reduces the risk of unexpected repair costs after purchase.

Used 100 Series LandCruiser inspection Perth helps buyers identify expensive mechanical problems before purchasing one of Australia’s most sought-after four-wheel drives. During our inspection of this turbo diesel 100 Series LandCruiser in Hillarys, we found several mechanical, suspension and body faults that buyers should understand before committing to the purchase.

The Toyota 100 Series LandCruiser has earned an excellent reputation for durability and off-road capability. However, most examples are now over twenty years old, so age-related wear becomes just as important as kilometres travelled. A professional inspection can reveal hidden problems that are difficult to spot during a quick inspection or short test drive.

Vehicle Interior

We started by inspecting the locks, controls and interior components.

We found that the driver’s door lock was broken and would not accept the key. The rear door lock also failed to operate, and the surround for the rear door lock was missing.

These faults affect both convenience and security. Replacement locks and matching keys can become expensive, particularly if several locks require replacement or re-keying.

The rear wiper blade also needs replacing to maintain good visibility during wet weather.

Engine Bay Inspection

Our inspection uncovered several maintenance concerns in the engine bay.

We found corrosion developing on the radiator hoses, which suggests they are ageing and should be monitored or replaced before they fail.

We also found oil leaks along the left-hand side of the engine and additional oil leakage from the power steering system.

The coolant appeared dirty, indicating the cooling system is due for servicing. Neglecting coolant maintenance can shorten the life of the radiator, water pump and engine.

We tested both batteries and found the passenger-side battery below specification. A weak battery can create starting problems and place extra strain on the charging system, particularly on a turbo diesel LandCruiser.

Steering, Brakes and Suspension

Our inspection identified several wear items underneath the vehicle.

The steering box is leaking oil and will eventually require repair.

We also found wear in the front suspension bushes and additional wear in the rear leaf spring and control arm bushes. Worn suspension bushes reduce handling precision and often contribute to uneven tyre wear and poor ride quality.

The transfer case is leaking oil, which should not be ignored. Low oil levels can accelerate wear inside the transfer case and lead to costly repairs.

We also found grease leaking from the clamp on the right-hand inner CV boot. Repairing this fault early may prevent contamination and help extend the life of the CV joint.

Surface rust is visible on the rear shock absorbers and suspension components. While the rust appears consistent with age, buyers should continue to monitor these areas during future servicing.

Chassis and Body Condition

Age-related deterioration was also evident around the exterior.

All window seals have cracked and started to deteriorate. Perished seals often allow wind noise and water leaks into the cabin.

The driver’s door handle is faulty, and the rear door lock cover is missing.

We also found areas where the clear coat has started to peel away from the paintwork. Although this issue is cosmetic, repainting affected panels can become expensive if the deterioration continues.

Road Test Findings

During our road test, we noticed a slight brake shudder under braking.

Brake shudder commonly results from disc rotor wear or uneven rotor surfaces. We recommend inspecting the brake discs and pads to determine whether machining or replacement is required.

Overall Assessment

Our used 100 Series LandCruiser inspection Perth uncovered several issues that buyers should factor into the purchase price.

The most significant concerns include multiple oil leaks, a leaking steering box, transfer case oil leakage, worn suspension bushes and a weak battery. The ageing window seals, faulty locks and deteriorating paint also add to the overall repair costs.

Despite these faults, many 100 Series LandCruisers remain excellent long-term vehicles when owners maintain them properly. However, buyers should always understand the repair costs before purchasing an older turbo diesel four-wheel drive.

A professional used 100 Series LandCruiser inspection Perth gives buyers the confidence to negotiate a fair price, budget for future repairs and avoid unexpected surprises after taking ownership.

Many are excellent vehicles, but because of their age, a professional inspection is highly recommended before purchase to identify mechanical wear and negotiate the correct price.

Mitsubishi Outlander pre purchase vehicle inspection Perth helps buyers uncover hidden mechanical, electrical and safety issues before purchasing a used vehicle. During our inspection of this Mitsubishi Outlander in Belden, we found several faults that could affect reliability, safety and future repair costs. A professional inspection gives buyers the information they need to negotiate confidently or avoid an expensive mistake.

The Mitsubishi Outlander remains one of Perth’s most popular family SUVs because it offers good practicality, comfort and value for money. However, like any used vehicle, regular wear and hidden faults can quickly turn a bargain into an expensive purchase. Our inspection covered the interior, electronic systems, engine bay, suspension, tyres, body condition and a comprehensive road test.

Vehicle Interior and Electronic System Checks

We started by checking the vehicle’s interior and electronic systems before carrying out a full diagnostic scan.

The rear wiper blade needs replacing to maintain clear visibility during wet weather.

Our diagnostic scan also revealed three fault codes relating to the rear parking sensor system:

• B253D – Left-hand rear centre parking sensor circuit fault
• B253L – Right-hand rear parking sensor circuit fault
• B253B – Left-hand rear corner parking sensor fault

These fault codes suggest problems within the rear parking assistance system. The issue may involve faulty sensors, damaged wiring or poor electrical connections. While these faults do not normally affect how the vehicle drives, they reduce the effectiveness of the parking assistance system and should be repaired.

Engine Bay Inspection

We tested the battery and found it well below specification.

Although the battery carries a rating of 600 Cold Cranking Amps (CCA), our test measured only 322 CCA, indicating the battery has lost a significant amount of its starting capacity.

A weak battery can cause difficult starting, especially during colder weather, and may also contribute to electrical faults on modern vehicles.

We also found cracks and splits in the fan belt.

A cracked drive belt can fail without warning, leaving the vehicle without charging, power steering assistance or air conditioning. Replacing the belt before it fails is far less expensive than dealing with a roadside breakdown.

Steering, Brakes and Suspension

Our inspection found excessive shoulder wear on both rear tyres.

Shoulder wear often indicates incorrect wheel alignment, worn suspension components or incorrect tyre pressures. Simply fitting new tyres without correcting the underlying cause may result in the replacement tyres wearing out prematurely.

We recommend checking the wheel alignment and suspension before fitting new tyres.

Chassis and Body Condition

Our inspection found several cosmetic faults around the vehicle.

The left-hand door seal is hanging loose and should be refitted or replaced to prevent water leaks and excessive road noise.

We also found large cracks or heavy scratches in the right-hand side repeater light lens. Damaged lenses can allow moisture into the light assembly and may eventually cause electrical problems.

The spare tyre has worn beyond its serviceable limit and needs replacing before you rely on it during an emergency.

We also found a broken aerial mount. Although this fault mainly affects radio reception, it may also allow water to enter if left unrepaired.

Road Test Findings

During our road test, we found the Mitsubishi Outlander consistently pulled to the left-hand side.

Several issues can cause a vehicle to pull, including incorrect wheel alignment, uneven tyre wear, worn suspension components or tyre pressure differences. Because the rear tyres already show significant shoulder wear, we recommend carrying out a complete wheel alignment and suspension inspection before purchasing the vehicle.

A vehicle that pulls to one side can become tiring to drive and may indicate suspension or steering issues that require attention.

Overall Assessment

Our Mitsubishi Outlander pre purchase vehicle inspection Perth uncovered several issues that buyers should understand before purchasing this vehicle.

The most significant concerns include the weak battery, three parking sensor fault codes, a cracked fan belt, excessive rear tyre wear and the steering pull during the road test. Although the remaining body faults are relatively minor, they still add to the overall repair costs.

None of these issues automatically make the vehicle a poor purchase. However, buyers should factor the cost of repairs into the purchase price and ask the seller to explain the cause of the steering pull before committing to the vehicle.

A professional Mitsubishi Outlander pre purchase vehicle inspection Perth helps buyers make informed decisions, negotiate with confidence and avoid unexpected repair bills after taking ownership.

Frequently Asked Questions

Can a weak battery cause electrical fault codes?

Yes. A weak battery can create voltage fluctuations that trigger electrical faults or communication errors on modern vehicles.

What causes shoulder wear on tyres?

Incorrect wheel alignment, worn suspension parts and incorrect tyre pressures commonly cause excessive shoulder wear.

Are parking sensor faults expensive to repair?

Not always. A technician may only need to replace a faulty sensor or repair damaged wiring, although diagnosis is essential before replacing parts.

Should I buy this Mitsubishi Outlander?

The vehicle may still represent good value if the purchase price reflects the repairs it needs. A pre-purchase inspection helps you understand those repair costs before you commit to buying.

Buying a used SUV can be an excellent investment, but only if you know exactly what you’re purchasing. This 2015 Honda HR-V prepurchase vehicle inspection Perth was completed by CMM Automotive at Melville Motors in Attadale to identify hidden faults before the customer committed to buying the vehicle.

The Honda HR-V has built a solid reputation for reliability, fuel economy and practicality, making it a popular choice for Perth drivers. However, even dependable vehicles can develop expensive problems as they age. A professional inspection helps uncover mechanical, electrical and safety issues that may not be obvious during a short test drive.

2015 Honda HR-V pre purchase vehicle inspection Perth helps buyers uncover hidden faults before purchasing a used vehicle. During our 2015 Honda HR-V pre purchase vehicle inspection Perth at Melville Motors in Attadale, we found several mechanical, electrical and cosmetic issues that could affect the vehicle’s safety, reliability and overall value.

Vehicle Interior and Electronic System Checks

One of the first concerns identified during this inspection was the presence of multiple diagnostic fault codes.

The scan tool detected the following:

• Electric Park Brake Power Supply fault (U-30016)
• Vehicle Stability Assist malfunction (U-04168)
• VSA Modulator Control Unit power supply fault (61-11)

Although dashboard warning lights may sometimes be cleared before a vehicle is offered for sale, these stored fault codes indicate there are electrical issues that require further diagnosis.

Modern Hondas rely heavily on electronic safety systems. The electric park brake and Vehicle Stability Assist (VSA) system work together to help maintain vehicle control and braking performance. Any interruption to the power supply or communication between these systems should be investigated before purchase.

Electrical faults can sometimes be as simple as a weak battery, but they may also indicate wiring problems, poor earth connections, charging system faults or control module failures.

Engine Bay Inspection

During the engine bay inspection, the battery tested below specification.

A weak battery can create numerous electronic fault codes, particularly on late-model vehicles with sophisticated control systems. Before replacing expensive modules, the battery and charging system should always be tested and repaired if necessary.

Another issue noted was a minor noise coming from the air conditioning compressor area.

The noise appears consistent with early wear in the air conditioning compressor bearing. While the air conditioning may still operate correctly, noisy compressor bearings rarely improve with time. If ignored, bearing failure can eventually damage the compressor, belt or clutch assembly, leading to a significantly more expensive repair.

Steering, Brakes and Suspension

The front lower control arm bushes were beginning to show minor cracking.

Small cracks are common as suspension bushes age, but they should be monitored carefully. As deterioration progresses, worn bushes can affect steering precision, braking stability and tyre wear.

The left-hand front alloy wheel also showed evidence of kerb damage.

Although cosmetic in many cases, heavy kerb impacts can sometimes affect wheel balance or even bend the rim. A close inspection is recommended whenever significant wheel damage is present.

Tyre Condition

Tyres were one of the biggest concerns during this inspection.

The front tyres were worn beyond their useful service life and require replacement.

The rear tyres showed noticeable scalloping.

Scalloped tyres often produce a humming or droning noise while driving and usually indicate suspension wear, poor wheel alignment or tyres that have spent long periods running out of balance.

Replacing tyres without correcting the underlying cause may simply result in premature wear occurring again.

Chassis and Body Condition

Several areas of exterior body damage were identified.

The inspection found:

• Damage to the left-hand front moulding
• Damage to the left-hand side skirt moulding
• Left-hand rear side skirt moulding damaged and incorrectly fitted

While these faults are primarily cosmetic, incorrectly fitted body mouldings can indicate previous repairs or impact damage. Loose trim pieces can also detach while driving and should be repaired properly.

Whenever multiple damaged exterior trims are found on one side of a vehicle, it is worth investigating whether the vehicle has previously suffered side impact damage or poor-quality repairs.

Road Test Findings

During the road test, we heard a noticeable noise while driving.

The noise appeared to originate from either the tyres or the wheel bearings.

The badly worn front tyres and scalloped rear tyres prevented us from positively identifying the source of the noise during the inspection.

Fit new tyres first, then road test the vehicle again. If the noise remains, inspect the wheel bearings to determine whether they are causing the problem.

This is an excellent example of why replacing worn tyres before diagnosing bearing noise is often the most logical and cost-effective approach.

Overall Assessment

This 2015 Honda HR-V pre purchase vehicle inspection Perth uncovered several issues that every buyer should consider before purchasing the vehicle.

The most significant concerns were the multiple electronic fault codes relating to the Vehicle Stability Assist and electric park brake systems, the low battery, worn tyres, scalloped rear tyres and possible air conditioning compressor bearing noise.

The suspension bushes are beginning to show age-related wear, while the damaged body mouldings suggest the vehicle may have experienced cosmetic damage. We recommend investigating the previous repairs before buying the vehicle.

None of these faults automatically make the vehicle a poor purchase, but they should certainly influence the purchase price. The electrical faults should be diagnosed properly before any commitment is made, as repair costs can vary significantly depending on the root cause.

A professional Honda HR-V inspection Perth provides buyers with the confidence to negotiate repairs, request a lower purchase price or walk away from a vehicle that may become unexpectedly expensive to own.

At CMM Automotive, our mobile pre purchase vehicle inspections help Perth buyers make informed decisions by uncovering hidden problems before money changes hands.

Frequently Asked Questions

Is a weak battery enough to trigger Honda VSA fault codes?

Yes. A low battery voltage can generate multiple communication and stability control fault codes. Replace the battery first, then retest the fault codes to confirm whether an underlying electrical problem still exists.

What causes scalloped tyres?

Worn suspension components, poor wheel alignment, wheel balancing issues and faulty shock absorbers commonly cause scalloped tyres.

Is a noisy air conditioning compressor expensive to repair?

It depends on the cause. A worn compressor bearing may be repairable early, but if left too long the entire compressor assembly may require replacement.

Should I buy a Honda HR-V with these faults?

The vehicle may still represent good value if the purchase price reflects the required repairs. A thorough inspection allows buyers to negotiate confidently and avoid unexpected repair bills later.

Car AC Not Turning On? Here’s What Could Be Wrong

If your car AC not turning on or suddenly blowing no cold air, it can make driving uncomfortable—especially during Perth’s hot summer months. Sometimes the problem is simple, such as a blown fuse or a faulty switch. In other cases, it may indicate a refrigerant leak, compressor failure or an electrical fault that requires professional diagnosis.

The good news is that most air conditioning problems give warning signs before major repairs are needed.

At CMM Automotive, we provide a professional mobile car air conditioning service throughout Perth, diagnosing air conditioning faults at your home or workplace so you can get back to driving in comfort.

---

Check the Simple Things First

Before assuming there’s a major fault, there are a few basic checks you can perform.

Ask yourself:

• Is the AC button switched on?
• Is the blower fan operating?
• Are all fan speeds working?
• Is the temperature set to cold?
• Is the engine running?
• Has the problem appeared suddenly?

If everything appears normal but there is still no cold air, professional testing is recommended.

---

Low Refrigerant Is One of the Most Common Causes

Modern air conditioning systems rely on the correct amount of refrigerant.

If the refrigerant level becomes too low because of a leak, many systems will prevent the compressor from operating to protect it from damage.

Common signs include:

• Air is no longer cold.
• Compressor does not engage.
• Cooling gradually became weaker.
• The system worked normally last summer but not now.

Simply adding more refrigerant without finding the leak usually provides only a temporary solution.

---

Compressor Problems

The car AC compressor is responsible for circulating refrigerant through the system.

If the compressor or compressor clutch fails, the system cannot produce cold air.

Symptoms may include:

• No cooling at all
• Clicking noises
• Grinding sounds
• Compressor clutch not engaging
• Intermittent cooling

Professional diagnosis determines whether the fault is mechanical, electrical or refrigerant related.

---

Electrical Faults Can Stop the Entire System

Modern vehicles rely on numerous electrical components to operate the air conditioning system.

Problems may involve:

• Blown fuse
• Faulty relay
• Pressure switch fault
• Wiring issues
• Faulty climate control module
• Failed sensor

These faults often require specialised diagnostic equipment to identify accurately.

---

Cooling Fans May Be the Problem

Many people assume the compressor has failed when the real problem is insufficient airflow through the condenser.

If the radiator or condenser cooling fans aren’t operating correctly:

• Air may feel cool while driving.
• Cooling disappears at traffic lights.
• Air becomes warm when idling.
• System pressures increase.

Cooling fan faults are relatively common and should always be checked during diagnosis.

---

Could the Cabin Filter Be Blocking Airflow?

A severely blocked cabin air filter can restrict airflow through the evaporator.

While it usually won’t stop the air conditioner producing cold air, it can make the system feel much less effective.

Replacing the cabin filter is a simple maintenance item that helps improve both cooling performance and cabin air quality.

---

Did You Know?

Did You Know?

Many drivers assume their air conditioner only needs a regas when it stops cooling.

In reality, low refrigerant is only one of many possible causes. Electrical faults, compressor problems, sensors and cooling fan issues can all produce similar symptoms.

How We Diagnose Air Conditioning Faults

At CMM Automotive, we don’t guess—we diagnose.

Our mobile car air conditioning service includes a systematic inspection of the entire system to identify the real cause of the problem before recommending any repairs.

Our inspection may include:

• Refrigerant pressure testing
• Compressor clutch operation
• Electrical testing
• Fuse and relay checks
• Cooling fan inspection
• Leak detection
• Vent temperature testing
• System performance testing
• Visual inspection of hoses and components

This process helps avoid unnecessary parts replacement and ensures the correct repair is carried out.

---

Why You Shouldn’t Ignore No Cold Air

Driving without air conditioning may seem like a minor inconvenience, but continuing to operate a faulty system can sometimes lead to more extensive repairs.

For example:

• A refrigerant leak may worsen over time.
• A struggling compressor may eventually fail completely.
• Electrical faults can become more difficult to diagnose.
• Moisture entering the system can damage internal components.

Addressing the problem early is often the most cost-effective option.

Frequently Asked Questions

Why is my car AC not turning on?

Common causes include low refrigerant, a faulty compressor, blown fuse, electrical fault, pressure switch failure or a damaged relay.

Why is my car AC blowing no cold air?

Low refrigerant, compressor failure, condenser cooling fan issues or electrical faults are among the most common reasons.

Can a blown fuse stop the air conditioner working?

Yes. A blown fuse or faulty relay can prevent the air conditioning system or compressor from operating.

Does my car always need a regas if the AC isn’t cold?

No. While low refrigerant is a common cause, compressor, electrical or sensor faults can produce the same symptoms. A proper diagnosis is recommended before regassing.

How long does it take to diagnose an air conditioning fault?

Most inspections take between 45 and 90 minutes, depending on the symptoms and the testing required.

How Does Car Air Conditioning Work?

Have you ever wondered how does car air conditioning work? Most drivers simply press the AC button and enjoy cool air without giving much thought to what happens behind the scenes. In reality, your vehicle’s air conditioning system is a carefully engineered refrigeration system that continuously removes heat and humidity from the cabin, keeping you comfortable even during Perth’s hottest summer days.

Although the system looks complicated, it actually works by moving refrigerant through a sealed circuit where it repeatedly changes from a gas to a liquid and back again. Each major component has a specific job, and if any one of them fails, your air conditioning may stop cooling properly.

At CMM Automotive, we provide a professional mobile car air conditioning service throughout Perth, diagnosing and repairing air conditioning faults at your home or workplace.

---

The Five Main Components

Your vehicle’s air conditioning system consists of several major components working together.

These include:

• Compressor
• Condenser
• Receiver drier
• Expansion valve
• Evaporator

Each component performs a different function in the cooling process.

---

The Compressor – The Heart of the System

The compressor is often called the heart of the air conditioning system.

Driven by the engine via a belt or electrically on some hybrid and electric vehicles, the compressor circulates refrigerant throughout the entire system.

Its job is to compress low-pressure refrigerant gas into high-pressure gas before sending it to the condenser.

Without the compressor, refrigerant cannot circulate and the air conditioner cannot produce cold air.

---

The Condenser – Removing Heat

After leaving the compressor, the hot high-pressure refrigerant flows into the condenser.

Located at the front of the vehicle behind the grille, the condenser works much like a radiator.

As outside air passes through the condenser, heat is removed from the refrigerant.

This causes the refrigerant to cool and change from a hot gas into a high-pressure liquid.

---

The Receiver Drier

The receiver drier has two important jobs.

It:

• Removes moisture from the refrigerant.
• Filters small contaminants from the system.

Moisture inside an air conditioning system can cause corrosion and reduce cooling performance, so keeping the refrigerant clean and dry is extremely important.

---

The Expansion Valve

Next, the refrigerant passes through the expansion valve.

This small component creates a sudden pressure drop.

As pressure falls, the refrigerant rapidly cools before entering the evaporator.

This is one of the key stages in producing cold air.

---

The Evaporator – Cooling the Cabin

The evaporator sits inside the dashboard.

Warm cabin air is blown across the cold evaporator by the blower fan.

As air passes across the evaporator:

• Heat is absorbed into the refrigerant.
• Moisture condenses into water.
• Cold, dry air enters the cabin.

This is why you often see water dripping underneath your vehicle after using the air conditioner—it is simply condensation draining away from the evaporator.

---

The Refrigerant Starts the Journey Again

Once the refrigerant absorbs heat inside the evaporator, it returns to the compressor as a low-pressure gas.

The entire cycle then repeats continuously while the air conditioner is operating.

This sealed cycle is what keeps your cabin cool, even on Perth’s hottest summer days.

---

Did You Know?

Did You Know?

Your car’s air conditioner doesn’t actually create cold air.

Instead, it removes heat from inside the cabin and transfers that heat outside the vehicle.

That’s why air conditioning performance depends on every component working together properly.

What Can Go Wrong?

Although the air conditioning system is reliable, problems can develop over time.

Some of the most common faults include:

• Refrigerant leaks
• Compressor failure
• Condenser damage
• Blocked receiver drier
• Faulty expansion valve
• Electrical faults
• Cooling fan problems
• Blocked evaporator drain

Any of these faults can reduce cooling performance or stop the system working altogether.

---

Why Regular Servicing Is Important

Like any mechanical system, air conditioning performs best when it is inspected regularly.

Routine servicing can help:

• Detect refrigerant leaks early
• Maintain cooling efficiency
• Protect the compressor
• Extend component life
• Identify worn parts before they fail

Preventative maintenance is usually much less expensive than replacing major components.

---

Why Perth Drivers Depend on Reliable Air Conditioning

Perth experiences long periods of hot weather, placing heavy demand on vehicle air conditioning systems.

A properly operating air conditioner doesn’t just improve comfort—it also helps demist windows, reduces driver fatigue and makes daily driving far more enjoyable.

Having your system professionally inspected before summer helps ensure it performs reliably when you need it most.

Frequently Asked Questions

How does car air conditioning work?

A car air conditioning system removes heat from inside the cabin by circulating refrigerant through the compressor, condenser, receiver drier, expansion valve and evaporator. The refrigerant repeatedly changes between a gas and a liquid, allowing it to absorb heat from inside the vehicle and release it outside.

Does a car air conditioner make cold air?

No. It removes heat and humidity from the cabin, making the air feel cooler and more comfortable.

Why does water drip underneath my car when the AC is on?

This is normally condensation draining from the evaporator and is usually a sign that the air conditioning system is working correctly.

What is the most important part of a car AC system?

Every component is important, but the compressor is often considered the heart of the system because it circulates the refrigerant.

How often should my air conditioning be inspected?

Having your air conditioning system inspected every one to two years is good preventative maintenance, especially before Perth’s summer.
