My AC stopped working in my 1994 Cadillac Deville. It is not a "coolant issue" My question is "Does my car have a fan or compresser?" what actually "blows"the air out of the vents and where is it located? also what important info would I need to know before performing this repair myself.

Re: Air conditioner not working.
If your just talking about the fan, the fan is the blower motor. Behind your glove-box is a black plastic box that houses the evaporator(which the blower blows on to give you cold air, the heater-core ( which the blower blows on to give you heat). Your car has both components, the compressor is mounted in front of your car's engine and the fan, you know. Most likely you won't be able to handle repairing the a/c system. You can buy 1lb. cans to charge your a/c but repairing it requires special tools, gauges, temp. readings, containment systems,and so on. But if there is something specific that you want to attempt then ask and 'll try to help.

hole in radiator. water pump leaking. leaking coolant into cylinder head from bad gasket. bad radiator cap can cause it to loose coolant . also check the hose to overflow resivore.coolant could be boiling away due to overheating. check the thermastat and the fans. all fuses and relays.as far as the codes check the wiring. if u have to unplug all the connectors and remove the loom and visualy inspect the wiring harness. i had to do this on my 93 deville. i found the reason my ac wasnt working my cruse control . and throttle position sensor. my temp sending unit was seting the idiot light . and the alternator was seting the charge light. all becase of a bad spot in the wiring. i seperated the wiring and tapped each individual wire up. re loomed it and taped over the loom . now my car runs and drives as if i drove it off the show room floor.amazing what a few hours of checking and repairing a few wires willl do. the cadillac dealer ship estimated around $2,000 to fix my problems depending on hours involved at $100 an hr. it cost me 2 rolls of electrical tape and $10 in loom. and like i said a few hours.
check the compressor with the ac running and make sure the compressor is kicking in and out in not the compressor might be bad or te clutch on te front of te compressor, sometimes u can get to much freon in them to i did it ounce
the problem could be the engine coolant tempature sensor. all1992 through 1994 models equipped with electronic climate control can display trouble codes.replace coolant temp sensor.if problem contines have powertrain control module checked
