Cadillac DeVille

Check for a clogged catalytic convertor

i have a 2000 cadillac seville and stability system is on.

write to my email at dpandcsdude@sbcglobal.net and i will try to scan and send you a diagram

Access the speakers through the trunk. Under the rear deck you can see the magnet of the speakers. I think they just unscrew out from there.

Unless the engine is completely seized it should still start with a low oil level. Not a good idea to try, though.

Try turning them off. This is done with the dimmer control of the dash lights.

you have a problem with theft system possible key cylinder

No. WikiAnswers does not support pictures or diagrams.

mine is under the seat

One would expect motor oil to be brown.

you have to remove the radiator and the a/c condenser to pull alternator also cooling fans

It could but I dought it is that dirty. It would most likely slip. Old transmissions use to have a modulator valve that told it when to shift. Now its done electronically through the computer . Look closely for any wires going to the tranny and check them for loose connections,corrosion,etc Answer The modulator valve used in some transmissions is operated by vaccuum so a vaccuum leak may also be the culprit. Another possibility may be the TV (throttle valve) sticking, or being bent inside the transmission. Your transmission is electronically controlled and is either a 4t60E or 440 T4 (Cadillac was transitioning from the latter to the former during the 1990 model year. From what I understand the 440 t4 was more prone to TV cable problems due to a difference in design with the superior 4t60E.

The letter C on an AC display on a 91 Cadillac Deville means cold. It is often the coldest setting available.

you need to replace your rotors in the front i had the same problem and the rear rotors had the entire car shaking but start with the front , good brands are centric or raybestoes, MAKE SURE THAT YOU DO HAVE ANYTHING ELSE BROKEN LIKE A BALL JOINT OR AXLE IN THE FRONT THIS CAN ALSO BE THE PROBLEM , ANY QUESTIONS EMAIL ME AT TWICHE23@AOL.COM , BUT ITS YOUR ROTORS

Check the low and high pressure switches, the AC fuse, and relay. Any of these can cause the AC to not get power to the clutch as if the freon is too low.

i have a 97 cadillac deville and the gas tank is 20 gallons.i would assume that it is the same on all of this model

It is attached just above the oil filter. You will need to put the front on jack stands. It is hard to remove and you need a sensor removal socket ($10 at autozone). The hard part is getting the plug off first. I am changing this now and when successful, will post full instructions.

First push OFF and WARM to retrieve codes, then push OFF and HI to clear codes ( Repairs must be completed or codes will return )

Bad flasher.

NOTE TO ALL THOSE WITH DEVILLE'S about 96 to 99. There are hundreds of complaints of these alternators failing prematurely and the ridiculous prices charged for a replacement. The cause of failure is because these accessory loaded cars work these high amp alternators hard and as a consequence they run hot, this however does not kill them, what does is that this heat is combined with that of the exhaust manifold and on a hot summer day you can fry eggs on your alternator. Yes you read it right, GM moron engineers put this high amp alternator tight against the manifold - no heat shields -nothing. As you sit at a light on a hot summer day with a lot of accessories going your alternator is just about glowing red under the hood. If your alternator is noisy or you have a strange whine from your northstar you can't identify, very hard to pinpoint, trust me its the bearing in the alternator. You do not need to pay the crooks $1,000.00 cdn for a new alternator, check your local yellow pages for a starter/alternator rebuilder and have them press new bearings into it for about $50.00 cdn. (Note that as the alternator is right at the front of the car in the slipstream as you are moving it is not as likely to fail as often as it will for those who spend considerable time in the city or idling) Now for the bad news, getting it out is a pain the first time, but as a Deville owner you will get to be an old hand at it and soon become an expert. The trick is that it will not come up through the top, it must be dropped out the bottom. First disconnect battery, remove the snap down plastic trim across the top of the rad, undo bolts and lift the fan assembly out, remove serpentine belt from the alt pulley, undo wires from alt. Next (not all years of Deville) look underneath the car directly under the alternator and you will find a small access plate, remove this and drop the alternator out. Like any thing else it looks formidable to tackle because your unsure, but it is actually quite painless, albiet a pain in the butt. An approach to solve this GM idiocy is to maybe get more expensive bearings from a bearing shop.

There are four ways to program most of these locks; refer to your owners manual for the proper sequence.

lock all the doors and open the car from passanger side. unlock all doors on passanger side and presto!! your car should start with no problems

If i am understanding your question coreectly you tighten them in a star pattern. if more then 5 lugs do the best you can!!!!!!!!!!!! This applies to all wheel lugs on any vehicle. keep in mind that one side will be reversed threads on an older vehicle such as yours. Don't try to bradk them loose turning them the wrong way or you will be replacing broken lugs!!!!!!!!!!!
