The hot air on the left side and the cold air on the right side of the air conditioner may be caused by the failure of the air door of the air conditioning system. It is necessary to disassemble the center console and check the air conditioning compressor, warm water valve, evaporation box and related temperature sensors.
Cleaning method of automobile air conditioner
1. Replace the dust filter. Traditional air conditioning system cleaning includes replacing filter element, using cleaner and removing filter element. The dust filters of most small cars are under the windshield of the car and covered by the running water tank. When replacing the dust filter, you can first open the engine cover, take off the clip that fixes the running water box, and take off the running water box to see the dust filter.
2. Disinfect the external circulation air duct, remove the dust filter, start the vehicle, turn on the air conditioner and put it in the external circulation gear, and spray foaming cleaning agent on the dust filter. The circulating air outside the air conditioner will suck the cleaning agent into the air duct, sterilize the decomposition products of the air duct, the evaporator of the air conditioner and the water tank of the heater, remove the odor, and the dirt will turn into liquid and flow out from the water outlet of the air conditioner. After the cleaning work is completed, it is best to replace the dust filter, and the air outlet inside the car will blow out fresh air.
3. Cleaning and replacing the dust filter and cleaning the air duct with detergent are all carried out outside the air conditioning system. If the air volume at the air outlet is still small after cleaning and the odor is not completely removed, you can only go to the repair shop to remove the bellows, replace the evaporator and manually clean the shell of the air conditioning heating device.
4. Sterilize the automobile air conditioner with ozone and high-concentration ozone water.
