What are the causes and solutions for BMW air conditioning not cooling?
1 Answers
Check whether there are no bubbles visible in the sight glass when the car air conditioning is running, and no bubbles appear after the compressor stops. During normal operation of the air conditioning, if there are continuous and slow bubbles in the sight glass, it indicates insufficient refrigerant. Use your hand to twist the belt at the middle of the drive belt; it should rotate about 90°. If the rotation angle is excessive, it means the drive belt is loose and should be tightened.
