You can pull the fuse for the compressor or slide under the car and disconnect the wire harness to the air pump.

SOURCE: im receiving a check coolant

No the light is linked to a sensor. There is a coolent sensor that tells you that the level is low. It sounds like the sensor has gone bad. And the sensor is located in the coolent tank. If it is bad from my understanding you have to replace the whole tank. But take a paper clip with the engine off and disconnect the wire harness from the sensor and jump the wires and see if the light goes off.

SOURCE: electronic leveling system

Yes. There is actually a GM TSB for switching the air ride system to regular gas shocks. It takes wiring in a relay to fool the body control module, and your ride will be slightly harsher. Check with your local GM dealership for the TSB which contains instructions and the required parts list

SOURCE: 97 cadillac deville

you either have a bad key...did you try more than one key?
Two other things can be wrong..
1) the igintion cylnder (where ya put the key in) has samll wires that sense the pellet in the keys for your car, and often they break, and the cylnder has to be replaced.
2) the passkey module has gone bad.
Either of these problems can be fixed by any compatent mechanic that has cadillac experience.

SOURCE: how to disable vats on

It's when the security light starts flashing that the infamous "chip" in the key becomes a nightmare to many. Gradually the car begins not cranking anymore or if it cranks it would start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
1st trick, Try a spare key that is newer or used less. The pins wear down and so do the keys causing security fail. 2nd trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shutting down while running, im sorry i have no quick fix... If anything on this page helps you, please remember to comment or give me a thumbs up on the myfixya sight so i can have a better rating to help more people on this. Thanks

Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.
----- http://vats.likeabigdog.com/


Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere from 600-1000 bucks. If you do buy this, please purchase it thru this link. The cost is the same, but i get credit for the sale and im trying to earn my money back, as you will be able to do if you buy fron NewRockies and join the free affiliate program. Thanks
----- http://newrockies.ca?ap_id=judd0081 ----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. Good info on both sites.

It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.

2000 cadillac deville is overheating, replaced thermostat: water pump radiator had head gaskets fixed it's saying check coolant level and it spews coolant from the overflow tank cap when hot thoughts?

Two cooling fans controlled by three relay's . If only one fan is working ,that could be a problem .
Coolant Level Sensor Description
The coolant level sensor monitors the coolant level in the cooling system and indicates if the coolant is low. This sensor is located at the base of the radiator surge tank and is not serviceable.
CHECK COOLANT LEVEL (2)
The IPC receives a discrete input from the engine coolant level switch. The engine coolant level switch is normally closed. When the engine coolant is low, the engine coolant level switch opens. When the IPC receives an open signal from the engine coolant level switch, the IPC displays the message on the DIC.

Relay Driven Dual Cooling Fan Diagnostics There are using a pontiac , by your cadillac is the same .

Hi, I was just wondering if anyone could tell me where the fuel filter on a 1990 cadillac sedan deville is. The car has a 4.5L pf1 v8, and i have heard that the fuel filter is somewhere

On the frame directly below the rear passenger door drivers side, above the E-brake cable and fuel return line. Be sure to loosen the fuel cap before loosening the outlet/inlet lines to the filter or fuel will continue to flow due to pressure in the tank also have a container to catch what fuel is in the filter/line. A 5/8 and 13/16 wrench should be the tools to use.

Water pump leak

Pumps leak at a 'weep" hole just under the pulley. This allows pump to let fluid escape after seal fails. Many pumps will continue to work for a long time before total failure. Just check radiator fluid level often. Your car may not justify an immediate fix due to cost of new pump replacement.

I HAVE A 1998 CADILLAC DEVILLE THE A/C/ WENT OFF AND THE COMPRESSOR WENT OFF HOW DO I RESET BOTH..

OK, if the A/C system has been discharged of R134a for any length of time, the car may have to be reset by disconnecting the battery and reconnecting after a few minutes.

That's the way my 1990 Cadillac Deville is, as it's a safety measure for preventing low freon level operation of the compressor which can damage the compressor.

My 1997 Cadillac Deville Limo hasn't had any leakage issues, so I don't know if this would work on that late of a Cadillac.

After adding r134a to the low side, and if the compressor doesn't work, then this could very well be your problem.

Good luck on this repair.

Have an 02 Cadillac Deville with 32k miles on it. Had a Cadillac dealer flush coolant and replace, and now every time I start the car the DIC reads "Check Coolant Level". Coolant level is fine. Now the...

Why replace the radiator it's just a bad sensor. Get the Haynes repair manual on your vehicle look up the water level sensor testing and replacement steps. The sensor probably cost around $30 and I doubt if it takes more than 30 minutes to replace.
