- When the refrigerant level is low, the AC system cannot properly cool the air, and the engine has to work harder to compensate. This can cause the engine to stall, especially at idle.
2. Compressor problems:
- A faulty compressor can also cause the car to stall. The compressor is the heart of the AC system, and if it is not working properly, the AC system will not be able to function properly. This can put a strain on the engine and cause it to stall.
3. Electrical problems:
- Electrical problems can also cause the car to stall when the AC is turned on. Faulty wiring, a faulty electrical switch, etc may not provide enough power to the AC compressor resulting in the car to turn off while AC is active.
Additionally, some other factors that can contribute to this issue include:
- A dirty or clogged air filter
-A faulty condenser fan
-Problems with the control module or sensors used by the air conditioning system.
