What to Do When the Baojun 510 Air Conditioning Doesn't Cool Properly?
3 Answers
Here are the specific reasons and solutions for the Baojun 510 air conditioning not cooling properly: 1. Insufficient or low refrigerant: This may be caused by a minor refrigerant leak. You can observe through the sight glass on the dryer tank. When the air conditioning is operating normally, if continuous bubbles appear in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it indicates severe refrigerant shortage. In this case, simply adding refrigerant will solve the problem. 2. Loose compressor drive belt: If the drive belt is loose, the compressor will slip during operation, leading to reduced transmission efficiency and decreased compressor speed. This results in reduced refrigerant compression and delivery, causing the car air conditioning to not cool properly. If the compressor drive belt is too loose, it should be tightened. If you can't turn it by hand, it means the belt is too tight and should be slightly loosened. If tightening doesn't work, or if the belt shows cracks, aging, or other damage, a new drive belt should be replaced.
My Baojun 510 also had air conditioning cooling issues last summer, possibly due to insufficient refrigerant or a faulty compressor. For self-inspection, first open the hood to check if the condenser fan is spinning—if not, the fan might be stuck. Then, inspect the air conditioning fuse in the fuse box to see if it's blown, and try replacing it. A dirty cabin air filter can also affect airflow temperature, so removing it for cleaning or replacement is crucial. If the problem persists, suspect a refrigerant leak or compressor failure—DIY repairs are risky, so I took it directly to a repair shop for technicians to test pressure and refill refrigerant with professional tools. In short, don’t wait until scorching heat to act; timely checks save trouble and protect car components. A broken AC makes the cabin unbearably stuffy and affects safe driving, so troubleshoot from simple to complex fixes.
As a long-time owner of the Baojun 510, I believe there are various reasons for poor air conditioning cooling. Simply put, it could be due to refrigerant leakage in the AC system, resulting in insufficient pressure and weak cooling; or the compressor belt might be loose, failing to pressurize. I remember one time when the cool air suddenly turned warm while driving, and upon inspection, it turned out that the evaporator pipes were clogged with debris—cleaning them fixed the issue. Regular maintenance is crucial: check the AC filter and refrigerant level seasonally, and keep the condenser surface clean and free of obstructions. If you've tried lowering the temperature but the air still feels warm, don't push through—pull over safely, open the windows for ventilation, and visit a nearby repair shop to test with a refrigerant gauge. Don't attempt DIY fixes to save money; the vehicle's electrical system is complex, and a professional diagnosis will quickly pinpoint the issue, ensuring safety and peace of mind.
