1, dirty or stuck throttle: the compressor will also work after the air conditioner works, and the compressor is driven by the engine, so the load of the engine will increase after the air conditioner is turned on, which means that the engine needs to increase the throttle opening and increase the air intake. When the throttle valve has carbon deposit or is stuck, it will cause engine jitter and abnormal noise.
2. Abnormal sound of air-conditioning pump: the abnormal sound of electromagnetic clutch and bearing in air-conditioning pump is mainly caused by the wear of electromagnetic clutch, and the abnormal sound of bearing in air-conditioning pump is mainly due to insufficient lubricating oil.
3. Poor tightness of compressor drive belt: the drive belt is too loose, and the electromagnetic clutch is easy to slip; If the drive belt is too tight, the load on the electromagnetic clutch will increase. Improper tightness of the drive belt will produce abnormal sound, and excessive belt will damage the air conditioner compressor.
