Common errors in car air conditioners

Air conditioner filter is clogged

After a long time of operation, the car's air conditioner filter will be covered with dust, preventing air from entering the interior. Car owners need to clean the air filter regularly to limit this problem.

The air conditioner condenser is dirty.

The condenser has the role of dissipating heat. If there is too much dirt, it will affect the heat dissipation capacity of the condenser. This reduces the cooling efficiency of the air conditioner. This leads to the condition that the air conditioner is not cold enough, not cold enough,...

Air conditioner gas shortage/leak

Gas is an important factor that determines the cooling capacity of a car's air conditioner. When there is a lack of gas or a gas leak, the car's air conditioner will not cool deeply or even not cool at all. When this happens, the car owner should check and refill the gas to ensure the air conditioner's operating capacity.

Fuse blown

If the fuse is blown, the compressor will stop working, causing hot air to escape into the car cabin. Therefore, even though the car air conditioner is on, it will not be cool.

Thermal relay failure

The car's air conditioner may not be cool because the temperature sensor relay is faulty. Therefore, the system will calculate the temperature incorrectly.
