What to Do When Wuling Hongguang's Air Conditioning Has Poor Cooling Effect?
2 Answers
Here are the specific reasons and solutions for the poor cooling effect of Wuling Hongguang's air conditioning: 1. Insufficient or low refrigerant: This may be caused by a minor refrigerant leak. You can observe it through the sight glass on the dryer tank. When the air conditioning is running normally, if there are continuous, slow bubbles in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it means the refrigerant is severely insufficient. In this case, simply adding refrigerant will solve the problem. 2. Loose drive belt of the car air conditioning compressor: If the drive belt is loose, the compressor will slip during operation, leading to reduced transmission efficiency and a drop in compressor speed. This results in decreased delivery of compressed refrigerant, causing the car air conditioning to not cool properly. If the compressor drive belt is too loose, it should be tightened. If it cannot be turned by hand, it means the belt is too tight and should be loosened slightly. If tightening is ineffective or the belt shows signs of cracking, aging, or other damage, a new drive belt should be installed.
I've encountered air conditioning cooling issues with my Wuling Hongguang after prolonged use. Driving in summer feels like being in a sauna, and the lack of cool air is really annoying. Last time I checked, the air filter was clogged with dust. Simply removing it for cleaning or spending a few dozen yuan to replace it with a new filter immediately restored the airflow. If the refrigerant is low, the compressor noise increases but cooling is insufficient—this requires a shop visit to check for leaks and top up the refrigerant. Dirt on the radiator surface also affects heat dissipation; try rinsing it with a hose. A non-spinning or slow-running fan is another potential issue—test its operation yourself. Don’t underestimate these problems; timely action can prevent worse situations. I recommend regular maintenance of the AC system, checking the filter condition frequently to reduce sudden failures.
