How does a car AC compressor break?
If your system’s refrigerant lines develop holes or cracks, the air conditioner leaks refrigerant. After a while, the level becomes so low that the compressor has to work harder to pump enough refrigerant through the system to cool your space. The strain can eventually cause the compressor to break down.
Why is my air conditioning not working in my Pontiac Grand Am?
If the controls feel fine, but have no effect on the air then it is probably a blown fuse. If you cannot hear the accompanying blowing sound when the air is turned from low to high, then the problem is in the blower motor. Disconnect the black negative battery cable first when looking for the blower motor.

Why is my car air conditioner cycling on and off?
I turned the A/C off and stopped putting R-134a into it becuase the compressor cycling was almost causing the car to die from the load it was putting on the engine. Onto Google I went. Everywhere I turned, people said that if the compressor was cycling on and off quickly, that meant the compressor was low on freon.
Why does my defroster turn off the AC in my car?
The AC removes moisture from the incoming air in order to keep the windows clear from fogging up. There are temps where the AC won’t run, the pressure switches and sensors will take care of that and turn off the compressor if the system is in danger of icing up.

Is it OK to demist without air conditioner?
Years ago, directing blower air onto the windshield didn’t automatically activate the air conditioner. Every car I’ve owned or driven recently turns the AC on in any air-flow position that includes the windshield. For demisting inside the car, this is sort of OK.
When does your defroster run the AC compressor?
