It's a normal process of "cycling", wherein the compressor is capable of moving more freon gas than the system is capable of handling. Pressure switches within the A.C. system switch the compressor on and off, in a normal cyclic state, to keep the pressures from going over a safe preset level.
There really are not any cons to having a quiet air compressor. The pros are many. There's nothing like a quiet running machine without all the clicks and clanks.
Compressor will normally run when in defrost mode.
Things to check first: Turn on the A/C control - open the hood and look at the compressor and observe whether or not the clutch is engaging (clicking on and off). If it isn't then check the fuse/electric relay that control the compressor. If the compressor operates but cycles rapidly (clicks on and off), that could be a sign of low refrigerant, have it checked. If these easy do-it-yourself checks are inconclusive then you need a mechanic.
a low pressure switch
More than likely it is low on refrigerant and the compressor is kicking off on the low pressure switch. After it is off for a few seconds the low pressure switch resets and starts up again, runs a few seconds and off again. Continuous cycle of off and on.
There are many reasons why an air conditioning compressor might not turn off. There is likely a wire that is not connected properly.
I repelaced the air conditioner compressor and the climate control unit. on the counsel, the compressor still reads, OFF and the air won't come on. is their a way to reset?
Probably low on freon.
When you have the heat on and select defrost / demist position to clear your windows , the air conditioning compressor cycles on and off to help de-humidify the air - at least that's the way it is on my 1995.
I believe even though you are getting cold air when you are under a load, you may still be low on freon. Being low will cause the compressor the click on and off. If you have a gauge to check the pressure in the system, that is where I would start to trouble shoot. If not, Try your mechanic, they can tell you if it is low. I would bet on that being your problem
Any air compressor that can achieve and hold 100psi will run an air gun. the larger the tank the more lugs you can remove before the compressor will need to run again.
Air suspension needs compressed air for the control of Air Springs (Air Spring is a cylinder like thing which goes up and down when air is pumped in and out of it). For pumping in and out the air, air compressor needs to be switched ON/OFF. Compressor relay connects and disconnects the compressor motor from the power supply ( battery).
