Why is the car air conditioning pipe frozen and no air coming out?
1 Answers
The reasons why the car air conditioning is frozen and no air is coming out are: 1. Clogged air filter: When the air conditioning is running, the outside air will be filtered through the air filter before entering the car, which can absorb a lot of debris in the air and easily become clogged. 2. Blower failure: If the blower is damaged, the car air conditioning will inevitably not blow air. Internal coil overheating damage or capacitor damage can cause blower failure. You can turn the car air conditioning speed and air volume to the maximum to listen to the blower sound to determine if there is a fault. 3. Problems with the car air conditioning control system: The air conditioning damper, control switch, or car air conditioning computer could be the cause of the fault. For example, expansion valve failure. If the expansion valve opening is too large, it can cause the evaporator temperature to be too low, leading to ice blockage, resulting in the air conditioning freezing and no air coming out. The expansion valve needs to be replaced.
