The most likely reason the compressor is not coming on is because you are low on freon. The low pressure switch will keep the compressor from cycling on because damage to your compressor would result. You can jumper across the low presure switch with the engine running and A/C turned on, ( for short time only) this will provide you with question is my compressor clutch good, or am I just low on freon. The AC compressor relay switch may need to be replaced

The AC clutch is on the front of the compressor where the belt rides. When power is applied to the clutch it engages to turn the compressor.

Yes. The serpentine belt will still go around the pulley and turn the compressor, but with no power to it, the AC will not work! Another option is to get a new belt that completely bypasses the compressor, but that may be more than you are willing to tackle.


What could cause your AC in your car to not to be cold and just blow air?

When you turn on the AC, check to see if the compressor is running. If the compressor clutch is not engaging, it might be as simple as low refrigerant level. Automobile AC is not like a home AC. Since the compressor cannot be sealed, the seal always leaks a little and you need to occasionally add a little refrigerant.


Why is car temp gauge going up when your ac is on?

when the AC is on it puts more stress on the engine cause the engine has to now turn the compressor. which in turn adds more heat to the engine.
