How accurate are the warning dashboard lights? On my last long distance trip, it said: "service engine soon". A Cadillac dealership told me the computer points to transmission. After hearing the amount of $1250.- plus, just to find the problem, I have decided to drive home, hell or high water. After another 800 mls , I am home now, DeVille sounds perfect and the %#&^*(  light is off. What is going on? Just in case: I did check my tr. oil and it is 100% full. Thanks.

Replying to: vladimir27 (Jul 07, 2008 11:08 am) The check engine lights are usually pretty valid. One thing that will set false errors, and usually will set a whole slew of them, is a bad battery, one with low voltage. Caddys do not like low voltage (and most modern autos are the same here), and if the voltage drops to 10 or 11 volts, this might be enough to start the car, but it may set a mess of codes, make 'strange' things appear on your digital dash, make certain components do strange things, etc, etc, etc. Your Cadillac has an extensive self diagnostic system which can easily be accessed by you. I'm not going into how to access or navigate thru this system. But, with the instructions, you can easily see the specific error 'codes' set. It will just be a number, but there are sites which will give you guidance as what general information is tied to each error code. IF it happens again, here is a link to a site with error codes and info on how to 'get into' the diagnostic system on cadillacs http://myweb.accessus.net/~090/dtcobd2.html Hosts: Please do not slap my hands about this. You told me a ciuple years ago, that if a question needed additional info found on another site, it was ok to post the link. I'm hoping that is all that I've done here. |

Thanks, bolivar. I will try the site. However since my confidence in DeVille is now big fat zero, I am thinking to replace it with Toyota or Subaru. |

I have just acquired a 1997 Cadillac DeVille 4Dr. that was in high water due to Hurricane Ike. The water got up over the bench part of the seats. I would like to know what all I would need to do to it so I will not harm it by driving it. I have changed the oil and the Trans. fluid doesn't seem to have any water. The power seats and windows do not work but it seems that everything else works O.K. Can someone suggest what all I should look for?

Replying to: joshlin1932 (Nov 05, 2008 1:02 pm) Anyway, this guy took a 2001 Deville. After starting on it, he then bought a wrecked 2000 Deville just for parts to transfer to his 'water' car. He posted lots of pictures. He worked on this car for many months, I think at least 6 or more. He completely dis-assembled the interior, removing seats, carpets, the dash, steering column. I won't go into what it was that he did to the motor and tranny, but it was much more than one oil change. I think he put like 5 or more flushes and refills of the tranny fluid. Things like alternator, power steering pump, etc were replaced. Basically if it was electronic, it had a large chance of not coming back to life. You've got sensors on the brake system for ABS, an ABS pump in the brake fluid system, etc, etc. You have modules in the doors for the electric windows, window motors, auto up, memory seats. Under the seats are power motors for the seats and a box driving the air bags. Every sensor in any part of the car could have water in it. You have dozens of connections in the electric system with each one having the possibility of future problems from the mud and corrosion. After all this work, he still was getting check engine lights and could not get it inspected. I don't remember exactly what he did, but he had to do something snaky to get it titled and licensed. If you have more than $500 in a 97 Deville that was under water, I think you have a problem. Nice running versions of this car should be able to be bought for four thousand dollars. I think a car like this should be scrapped for body parts. If the motor or tranny sits for any time at all with water in it (like 4 weeks), I would fear for the effects of rust. |

| I have a 1995 Sadan Deville. The A/C compressor does engage but does not blow . When I have the A/C on, I can feel cold air seeping from the vents. Any Ideas on what it could be? Also the air ride light keeps comming on telling me that it needs service. Can I disconnect this and install regular HD shocks on the car? | |

| I have recently bought a 99 deville and within a couple of weeks the car overheated and the dealership had to replace head gaskets and bolts. Now the car idles bad when first started then seems to run fine after fifteen minutes or so. The check coolant level light has also came on twice in the last two weeks causing me to have to put more coolant in. i am hoping that my gaskets are not going out again and am hoping it could be something alot cheaper to fix. | |

Need to replace "Select" radio station modual on steering wheel. Or Not. Issue- select station- up, and down functions properly. Modual doen not light up when lights are engaged. How do I disassemble wheel for replacement? Where do I locate part (modual)? Dealer only? Discribe replacement process-am mechanically inclined (LOL)?
