What causes uneven cooling in Toyota Reiz's air conditioning system?
1 Answers
When a car's air conditioning system delivers cold air on one side and warm air on the other, it typically indicates insufficient refrigerant. With inadequate refrigerant, the evaporation and heat absorption process of liquid refrigerant entering the evaporator ends prematurely. This results in cooling only on the side where refrigerant flows into the evaporator, while the outflow side shows no cooling effect. Consequently, only a portion of the air blown by the fan gets cooled, creating temperature differences between the vents. Below are air conditioning maintenance tips: 1. Comprehensive system inspection: During first summer use, examine the AC system thoroughly - check refrigerant levels via the receiver-drier, inspect if the cabin filter is overly dirty, and ensure the condenser has no debris. 2. Regular cleaning: Replace cabin air filters periodically to prevent musty odors. Additionally, schedule condenser cleaning (requires radiator removal for thorough cleaning).
