SOURCE: 1998 cadillac deville still reads service ac system

Sounds like you have a problem with the pressure switches on the ac system. Find the aluminum lines for the ac, attached to the lines are two pressure switches plugged in to the car wiring harness. Make sure the sensors are tight into the fittings on the lines. If they are unplug them one at a time and bridge the two terminals in the plug going to the car's harness not the switch, with a jumper wire or cotter pin which ever wire turns on the ac compressor remove that switch and take it in to the auto parts store and get another one.

hope this helps you out

you can locate the low limit switch and unplug it and use a wire to jump the terminals in the socket..that will start the compressor, car running of course, then add proper amt freon and plug switch back in
The switch should be on an ac line and have 2 wires

What does it mean when the dashboard reads gear indicator fault, service ride control and change oil soon even after i just got it changed along with service vehicle thats what keeps popping up on my dash...


Off the top of my head the following may be the case for your 1995 Cadillac Deville based on my 1997 Cadillac Deville knowledge:

gear indicator fault- has to do with the shift lever sensor down on the column by the feet,

service ride control- has to do with the air ride shocks in the back or the compressor in the front or the ride control height,

change oil soon- has to do with not resetting the % oil life (just press reset button for a few seconds when the oil % life is displayed)

Hope this helps you out.

My cadillac concours deville say low refrigerant ac compressor off and tried to put some in is there a certain way to do it


Yes, if it is like my 1990 cadillac deville, you must first disconnect the battery for 3 or so minutes and reconnect it to clear the error message and to reset the a/c system so it will turn on when R134a is added under pressure.

Cadillac did that in 1990 so the compressor would not run without refrigerant in the system. It's a safety feature designed to save a compressor if there is a leak in the system.

If you try to add refrigerant without resetting the a/c system, then the compressor will not engage.

My dash says that my ac compressor is off. How do


If you want to charge the system and the system was low on freon, it may have automatically shut the compressor down.

Sometimes, the computer will do this as a safety measure, and it must be reset.

On my 1990 Deville, resetting the computer is as easy as disconnecting the battery for a few minutes and reconnecting and making sure that as soon as your a/c compressor starts cycling to add some refrigerant, about .5 lbs. at least.

Otherwise, the compressor will not get current from the computer's relay.

Just brought used 94 cadillac deville ac works great but no heat


This is the the Cadillac Climate Control operates. When you press AUTO, the system will automatically maitain DESIRED temp . The A/C compressor will operate ALL THE TIME on AUTO. Don't want the a/c compressor to operate, PRESS " ECON". Air delivery will NOT be DE-HUMIFIED, nor will it cool, only warm,. Hope this helps.

1995 Cadillac Deville


In my 1990 Cadillac Deville there is a sticker that says that one can reset the computer that controls the compressor by disconnecting the battery for a few minutes and reconnecting.

Did you disconnect the battery to reset the a/c system?

The symptoms you are describing lead me to believe that there is a safety feature that prevents the compressor from engaging when the compressor has been run for any length of time without at least .5 lbs. of freon in the system.

You said that you had to run a hot wire to charge it up with freon. But, if you ran it without freon, it may have automatically invoked the 'safety' feature.

I have seen this happen on my 1990 cadillac. I haven't had any problems on my 1997 Cadillac Limousine, because I never had a low charge on that car.
