Hi there,
there are several test to be done and analysis on trouble shooting ac performance.if the ac run smoothly but insufficient cooling effect was taken after recharching factors can be obtain in poor performance of compressor,clogging of tubes mostly on capillary tube and expantion valve.this main factor
contribute on ac in sufficient cooling.compressor performance can check the on the discharge valve by mounting a hi side pressure gauge and check the lost compression effeciency.while the compressor is running if it can discharge a pressure higher than the operating pressure w/o losses on psg. you have good
compressor performance.but if can not maintain a operating pressure you replace compressor.if the compressor is good check the capillary tubing by purging and cleaning the system,obstruction can't expand the freon inside your evaporator,have a nice day don't forget to fix my rate.also recharge exact amount freon on the system don't exceed.poor refrigeration was the result,no cycle will occured.

93 cadillac deville. ac blowing hot. only one pound of freon but compressor wont kick on to allow for charging. where is the relay for the compressor, or what am i missing here? thanks

There is a sensor inline on one of the hoses or on the ac evaporator that should have 2 wires. Unplug the sensor and take a short piece of wire and make a U shape with it and plug it into both ends to complete the circuit on the wired side not the sensor. This will trick the AC pump to turn on. You will also be adding the can or two of freon. If the pump does not turn on after tricking it there may be a problem with the pump or a problem with wiring or the temp control.

1986 Cadillac sedan deville is my first car. the A/C doesn't work. Air blows out of the vents but it is not cold. I checked the fuse, that is fine. I don't really know what I'm doing, so any...

I would try charging the ac system with some freon,and see if that is the problem,the ac compressor will not come on unless the ac has freon,and enough to turn it on,disconnect the negative battery terminal for 25 seconds before doing this to reset the ac system.

2001 cadillac deville ac compressor not coming on

Try adding some refrigerant as it won't come on as a safety feature if it is too low in pressure.

Otherwise, it may be an electrical break in the clutch wires, or a bad fuse.

If it is like my 1990 Cadillac Deville, the a/c compressor will not come on at all until the battery is disconnected for several minutes and reconnected, and then charged with at least .5 lbs. of refrigerant.

How do i get the compressor to run to ad freon

If you're getting a AC error light, but you're sure the compressor works, you need to reset the compressor. Disconnect the battery for 20min (keep in mind, this will reset everything). After 20min, reconnect the battery. When you turn on the AC, the light shouild go out (AC error light). Be ready to add freon right away or the compressor will shut down again. Post back if you need instructions on adding refrigerant. Best of luck.

My ac does not blow cold in my 97 cadillac deville but it does blow just not cold and its n ot the fuse what can i do?

You probably have leaked out your freon after so much time. Try adding some more Freon if it doesnt stay charged you may have bigger issues.
