What to Do When the Car Air Conditioning Compressor Does Not Engage or Work?
1 Answers
Start the engine. Let it idle, then turn the temperature selection knob to the cooling position. Turn on the air conditioning switch and observe whether the compressor electromagnetic clutch engages. The compressor electromagnetic clutch engages, but the compressor does not operate. Check the fuses and the air conditioning relay. Use a digital multimeter to inspect the electromagnetic clutch control circuit, and verify whether the fuses and air conditioning relay are damaged. Check whether the internal pressure of the refrigeration system meets the specified requirements.
