Why is the car air conditioning compressor not turning?
2 Answers
Possible reasons for the car air conditioning compressor not turning include: 1. Insufficient refrigerant, which causes the computer to automatically stop the compressor. In this case, simply adding a certain amount of refrigerant can solve the problem. 2. It is also necessary to check whether the power supply and grounding of the air conditioning compressor are normal, whether the engine radiator and condenser are clean, whether the engine temperature is too high, and whether the air conditioning computer is working properly. These conditions can all cause the air conditioning compressor to stop working. 3. The primary reason for the compressor not working is prolonged use of the air conditioning system. Over time, severe internal wear can lead to the compressor failing.
Having driven for so many years, I've seen quite a few cases where the air conditioning compressor won't engage. The most common issue is a blown fuse - just open the fuse box, locate the corresponding position, and give it a gentle press to test. Another frequent problem is poor electrical contact, such as loose connectors or aged wiring causing a short circuit that prevents the signal from reaching the compressor. The compressor itself might be faulty too; if you don't hear a clicking sound when pressing the AC switch, you should suspect damage to the electromagnetic clutch or mechanical components. Insufficient refrigerant is also a major factor - when the high pressure is too low, the system automatically shuts down. When encountering such faults, never force it to work; go straight to the repair shop and let the mechanics test it with a multimeter. Regularly checking refrigerant levels during maintenance can prevent many troubles. Safety first - don't wait until summer when it's unbearably hot to take action.
