6 Signs Your Car’s AC Compressor Is Failing


If your car’s air conditioner is not working — or not working properly — then it is most likely the fault of the vehicle’s air conditioner compressor.

The AC compressor is considered to be the “heart” of the air conditioner. It is the pump that moves the refrigerant through the air conditioning system — thus the core of what makes your car’s AC works. If your air conditioner isn’t working as well as it should, then it is time to check the compressor. Failing to do so may lead to further damages to the air conditioner and may require you to replace the whole AC system altogether.

Are you wondering if your car’s AC compression is failing? Is it time to check out Mercedes 280sl parts in order to fix it? Here are seven signs to watch out for:

Unusual noise

Usually, the first symptom of a failing AC compressor is the presence of strange or unusual noises. It’s the first and simplest sign that says your AC compressor is beginning to falter and fail. When your AC is emitting strange sounds, it means some parts of the compressor may be worn out or damaged.


Another early sign of a failing AC compressor is leaking fluids. An air conditioning unit’s compressor usually has its own system or bearings that allow the prevention of fluid from dripping out of the system. A leak may mean some of the compressor’s parts or bearings may already be damaged and is always a clear sign that the parts have to be replaced.

Visual inspection

An often neglected symptom for when AC compressors fail is physical damage. Check the compressor and inspect it for any visual damage such as oil leaks or rust — these are usually signs that failure is imminent Subaru Business Contract Hire.

High temperature

After the noise and the leaks, it’s likely your car’s AC will have problems functioning properly. When your AC starts blowing warm air — or if it can no longer maintain cold temperatures as it used to — it may mean that the compressor is no longer able to regulate the flow of refrigerant in the system Subaru Used Car.


Is your car’s AC shaking when you turn it on? That’s almost always a sign that something is wrong with its compressor. The shaking means the unit is having a hard time turning on — if left unchecked, it will likely lead to permanent failure and breakage of your AC compressor.

Stuck clutch and tripping circuit breaker

When the clutch of your car’s AC ceases entirely, it is obviously a sign that its compressor is failing or has failed completely. The clutch is responsible for transferring power from the car’s engine to the compressor. In most cases, a failure like this means replacing the clutch entirely. Another serious sign of a damaged AC compressor is if turning the AC on trips the car’s circuit breaker. It may be a symptom that the compressor is overheating.

As the core of your car’s conditioning system, it is best not to neglect your AC compressor once signs of problems begin to arise. Check your Mercedes 280sl parts often to see if any repair or part changes should be done to prevent further and permanent problems to your car.
