How to Fix a Car Air Conditioning Compressor That's Not Working?
2 Answers
If the car air conditioning compressor is not working, the compressor must be replaced promptly; otherwise, the car air conditioning system will fail to provide cooling. A non-functional car AC compressor may result from the following reasons: 1. Insufficient refrigerant: Terms like refrigerant, coolant, Freon, or 'snow seed' commonly refer to the air conditioning refrigerant. Solution: Replenish the AC refrigerant. 2. Improper tension of the car AC belt: An overly tight belt can directly cause the compressor to seize and stop operating; a loose belt leads to slipping in power transmission, resulting in intermittent cooling and reduced efficiency. Solution: Adjust the belt tension. 3. Electrical system issues: Short circuits or open circuits disrupt the power delivery path, preventing the electromagnetic clutch from properly controlling the compressor's operation.
Last time I was on the highway, the AC suddenly quit and it was miserable. If the compressor isn't running, don't panic—it's probably a blown fuse or a bad relay in that little box under the steering wheel. If the compressor doesn't even hum, the control circuit might be faulty, like a bad temperature sensor sending wrong signals. If the belt is loose and slipping, you'll hear a squealing noise when you turn on the AC. You can check the fuse box yourself for any blackened fuses, but if the compressor clutch coil is bad, you'll need a repair shop. Oh, and for older cars, the most common issue is refrigerant leakage—if the pressure is too low, the compressor won't start at all. Check the AC vents for oil stains to see if there's a leak.
