Common errors in car air conditioners

The air conditioner filter is clogged.

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 it is covered with 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 leak/lack

Gas is an important factor that determines the cooling capacity of the 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.

Thermal relay failure

Car air conditioner not cooling may be due to a faulty temperature sensor relay. Therefore, the system will calculate the temperature incorrectly.
