What Causes the Left Side of Car Air Conditioner to Blow Hot Air While the Right Side Blows Cold Air?

[MaxAnn]

Air conditioner blowing hot air on the left side and cold air on the right side may be caused by a malfunction in the air conditioning system's air door. Below are the cleaning methods for car air conditioners: 1. Replace the dust filter: Regular air conditioning system cleaning includes replacing the filter, using cleaning agents, and disassembling for cleaning. In most compact cars, the dust filter is located under the front windshield, covered by the water trough. To replace the dust filter, first open the engine hood, remove the clips securing the water trough, and then take off the water trough to access the dust filter. 2. Disinfect the external circulation air duct: After removing the dust filter, start the vehicle, turn on the air conditioner, and set it to external circulation mode. Spray foam cleaner onto the dust filter area, and the external circulation air will draw the cleaner into the air duct, disinfecting the duct, air conditioner evaporator, and heater core, while also removing odors. Dirt will liquefy and drain out through the air conditioner's outlet.
