Why does my car AC only get cold when I’m driving?

Defected condenser fans can be among the major causes when air conditioning only works when driving. Condenser fans help reduce the refrigerant’s temperature to ensure it condenses. Malfunctions in condenser fans can prevent this from happening.

Why does my car AC only work when moving?

When the compressor is not functional, it finds it difficult to get cold, and the engine should put extra work into it to make it cooler. Therefore, when the car is not moving, the engine doesn’t work. As a result, neither the coils nor the cabin are cooled.

Why your AC is not blowing cold air when idle?

When a car is idling, the engine is not running at its full capacity. This means that the compressor in the AC system is not getting as much power as it needs to work properly. As a result, the refrigerant in the system may not be able to cool down enough to produce cold air.
