What Are the Reasons for Frozen Air Conditioning Pipes and No Airflow in Cars?
1 Answers
Here are the reasons for frozen air conditioning pipes and no airflow in cars: 1. Clogged Filter: When the air conditioning operates, outside air passes through the air conditioning filter before entering the car, trapping many airborne particles, which can easily clog the filter. A clogged air conditioning filter results in no airflow, leading to freezing of the air conditioning system. 2. Blower Motor Failure: A damaged blower motor can cause the air conditioning to stop blowing air. Overheating of internal coils or capacitor failure can lead to blower motor malfunction. If a fault occurs, it is necessary to promptly visit a 4S shop or repair facility for inspection and repair. 3. Control System Malfunction: For example, an expansion valve failure. An excessively open expansion valve can cause the evaporator temperature to drop too low, resulting in ice blockage and causing the air conditioning to freeze and stop blowing air.
