Reasons: Refrigerant leakage; In this case, you can replace the expansion valve and re-tighten the leaking high-pressure pipe connection. The air conditioning compressor has been used for a long time and has accumulated too much dust inside, so it should be repaired at an auto repair shop. Car air conditioning maintenance methods: 1. Comprehensive inspection of the air conditioner: When using the air conditioner for the first time in summer, first inspect the air conditioning system, such as checking the refrigerant and whether the air filter is too dirty or if there are foreign objects in the radiator through the liquid storage tank. 2. Pay attention to the cleaning of the air conditioner: The air filter should be replaced regularly. In areas with a lot of sand and dust, and where catkins are flying, they can stick to the filter, easily breeding bacteria and causing a musty smell in the air conditioner. In addition, the condenser should also be cleaned regularly, and the water tank should be removed for thorough cleaning. 3. Turn off the air conditioner in advance: After parking, do not turn off the air conditioner immediately. Generally, after reaching the destination, the owner turns off the air conditioner and leaves directly. Unlike in autumn and winter, the huge temperature difference between the inside and outside of the car in the hot summer can cause the air conditioning system to mold, leading to the growth of mold. Therefore, the owner should turn off the cold air a few minutes before reaching the destination, turn on the natural wind, allow the temperature in the air conditioning pipes to rise, eliminate the temperature difference with the outside, and thus maintain the relative dryness of the air conditioning system to avoid mold growth.
