Replace old wiring. Maintenance methods for car air conditioners: 1. Regularly check the refrigerant and compressor oil. The pressure on the low-pressure side of the air conditioning system should be 2 to 3 bar, and the high-pressure side should be 15 to 25 bar; 2. Clean the surface of the condenser. The cooling effect of the air conditioner is related to the cleanliness of the condenser fins. Dirt, insects, or debris on the condenser surface will reduce heat dissipation efficiency and affect cooling performance. Starting the air conditioning system under high pressure and heat can severely impact compressor-related components; 3. Clean the surface of the evaporator.
