1. Low refrigerant pressure: If the refrigerant pressure in your air conditioning system is too low, the compressor may not be able to build up enough pressure to turn the clutch and start the compressor. Check the refrigerant pressure and add more if necessary.
2. Bad compressor clutch: The compressor clutch is what engages the compressor to the engine. If the clutch is damaged or worn out, it may not be able to engage the compressor properly, causing it to stop turning. Check the clutch for damage and replace it if necessary.
3. Bad compressor: If the compressor itself is damaged, it may not be able to turn properly, causing it to stop and make a clunking noise. Check the compressor for damage and replace it if necessary.
4. Electrical problems: Electrical problems, such as a bad wiring connection or a faulty relay, can also cause the air compressor to stop working. Check the wiring and relay for damage and replace them if necessary.
If you are not comfortable troubleshooting and repairing the air conditioning system yourself, I would recommend taking your vehicle to a qualified mechanic for diagnosis and repair.
