What causes poor air conditioning cooling in Honda XRV?

[AmeliaMarie]

Here are the specific reasons for poor air conditioning cooling in Honda XRV: 1. Insufficient or low refrigerant: This may be caused by minor refrigerant leakage. You can observe through the sight glass on the dryer tank. During normal operation, if continuous bubbles appear 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 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 delivery, causing the car air conditioner to stop cooling. If the compressor drive belt is too loose, it should be tightened. If the belt cannot be turned by hand, it indicates excessive tightness and should be slightly loosened. If tightening is ineffective or the belt shows cracks, aging, or other damage, a new drive belt should be replaced.
