Reasons Why Car Air Conditioning Only Cools When the Vehicle is Moving
1 Answers
Reasons why car air conditioning only cools when the vehicle is moving are as follows: 1. Insufficient refrigerant. 2. Blocked expansion valve or clogged evaporator fins. 3. Clogged condenser fins or excessively high system temperature, resulting in poor cooling performance. 4. Leakage in the air conditioning system pipelines. 5. Insufficient pressure from the air conditioning compressor. 6. Blown air conditioning fuse, damaged wiring, short circuit, or poor connector contacts. Solutions for car air conditioning only cooling when the vehicle is moving are as follows: 1. Strengthen maintenance of air conditioning system components, ensure cleanliness of condenser fin surfaces to guarantee heat dissipation efficiency. 2. Conduct system pressure tests to confirm refrigerant charge levels and pipeline patency. 3. Check if fuses and connectors are functioning properly.
