Clutch problem with the compressor.Check drive pulley runs free when turned off and when you switch it on it should be tight.You have to remove the drive belt to do this.

The a/c compressor won't come on if the refrigerant is low...make sure you have the proper amount of refrigerant and you have no leaks in the system.....if that's ok then check the a/c compressor cut out switch mounted on the compressor itself, you can check for continuity on the switch with an ohm-meter or resistance meter....if the switch is closed, which it should be when the compressor is running...it will measure 0(zero) ohms which it should be.....or you can measure the voltage on both sides of the switch with reference to chassis or ground...which will show 12 volts on both contacts which it should be...good luck

Serpentine belt broke, and I am told I need a new compressor. We found one but it is from a seville with a northstar engine. Can I use this? Thank you


Hello: All Cadillac Devilles had a Northstar starting in 1996. It will not make any difference if it is a SLS (275 HP) or a STS (300 HP)

The airconditioner on my 2002 cadillac seville sometimes works but most of the time it doesnt. when it does it blows cold air. what could it be


There could be a blockage in a screen called an orifice tube in the liquid refrigerant line. The refrigerant may not be circulating properly and this can cause a pressure out of range (too high) which can kick off the compressor until the pressure is no longer out of range. Another possiblity is the compressor is nearing the end of its life and gets too "hot" and kicks off. I have seen some that would "smoke" from the clutch failing before any thermal limits would kick off the compressor, so I sort of doubt that's the issue. Another possiblity is a loose drive belt, but that would ordinarily present a belt noise (loud squeal). Another possiblity is the alternator is failing and cannot deliver sufficient current to run the electrical devices that kick on when the AC is running. A parts store can check that for you for free!

Need to change my a/c air compressor 1995 seville sts


you need to get a professional to remove the gas and then you can replace it. then get it evacuated and regassed. it would probably pay to replace the dryer also if the compressor has failed.

A.C compressor reads off on my dash. Also I refilled my refriderant and it didnt work. I own A 97 Cadillac Seville STS.


If it builds up too much pressure in the system it will shut off compressor. May be an AC pressure switch problem if compressor does not even come on.
