What will keep Ac compressor from coming on in a 2000 volkswagen beetle?

The cycle switch not engaging the Compressors clutch


Why wouldn't the AC compressor turn?

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


Ac compressor not coming on in a 1992 Buick?

Either low on freon or the low pressure switch is bad. You are gonna have to put a set of gauges on it. Usually this happens when the freon leaks out of the system. If there is not enough freon in the system, the low pressure switch keeps the compressor from coming on and being burned up.

What would cause the air suspension on a 2003 Lincoln navigator not to work?

there are several causes to the air pump. the first and most obvious is the air pump (compressor) itself. if you do not hear the compressor pumping air or if you do not feel the slight vibration of the compressor when you put your car into drive, then it's probably the compressor that has gone bad. if the compressor is coming on and you do not hear any air leaking, then your problem could be the height adjuster, located on the suspension bags themselves. Bronconvict: another possibility includes the compressor relay switch. This switch controlls the power to the air bag suspension compressor. This switch is known for burning out when the suspension compressor is working too hard. This can also be caused by a bad/corroded GEM module (due to notorious winshield leak). i had to replace "height sensor" on driver side . part was $200.

If the AC compressor clutch does not kick in and the relay and fuse are ok what could be the problem?

The clutch receives it's signal to engage from a pressure switch in the system. If there is insufficient refrigerant in the system the pressure switch will not close resulting in no power at the compressor clutch to make it engage.

Why does ac blow hot 96 Saturn sl1 with a charged system?

You first need to find out if your ac compressor is coming on. It should make a click sound then you can see the armature or compressor clutch pulley spinning. If it is not coming on then check ac relay, cycling switch, ac control head, wiring, and any associated fuses. All of these things can stop the compressor from starting


How do you get ac to blow cold compressor not kicking in?

Find out the reason the compressor isn't engaging, of course! It could be a problem with the clutch, a problem with the low pressure switch, a low refrigerant level (likely caused by a leak in the system which needs to be repaired), or the compressor itself could be defective. Without any sort of diagnosis, we have no way of narrowing down the causes. You won't get cold air without the compressor, so that has to be dealt with.
