If the car compressor is broken, except for the deterioration of the cooling effect of the air conditioner, it will not affect other working systems of the vehicle. Therefore, if the compressor is broken, at most there is no air conditioner blowing, and the vehicle can be driven as usual. To judge whether the compressor is damaged, you can turn on the air conditioner refrigeration switch and check whether the engine speed will increase. If the engine speed does not increase, it means that the compressor control circuit is broken, or the electromagnetic clutch of the compressor is broken.
The symptoms of a broken car air conditioner compressor are relatively obvious. If the electromagnetic clutch of the compressor is broken, it can be replaced separately, but some repair shops require a complete replacement; if the compressor piston is damaged, the compressor can only be replaced. Replace compressor.
How to use the air conditioner to avoid compressor failure is as follows:
1. The refrigerant should be filled in an appropriate amount, if it is too little, it should be filled, if it is too much, it should be released, otherwise the air conditioner should not be used;
2. When parking and idling, it is best not to turn on the air conditioner for a long time;
3. Do not turn on the air conditioner for a long time under the sun;
4. When the air-conditioning system breaks down, it should be checked in time, otherwise it will cause serious failure if it is used for a long time.
