Had the same problem, checked the internet. The solution is there. Built a bypass resister chain to match the resistance in the key chip, hooked in on the steering column wires under the dash and cut the key out of the loop. Car would not even start before, now starts fine and doesn't need security key. Cheaper than replacing the ignition switch and I could care less if the security system works. There's another way to bypass the security module if need be. Cost me $5 for the string of resisters you can buy at Radio Shack.

I had a similar problem on a 90 Seville. Checked out the wiring harness in the trunk area, found no problems. Replaced the tailight bulbs with new ones and the problem went away and never came back. Worth a try and cheap! I figure, I don't care if they whack the problem with a magic stick as long as it fixes the problem.

All my interior lights, door and compartment stopped working suddenly. Is this a fuse, relay, or circuit breaker issue? 2004 Deville

It's probably a 'short to ground' problem, that then blew a fuse.

Yes I have a 2002 DeVille and I have the same problem the rear door and the windows do not work from either place. In the manual it does say there is a fuse for this but It does not seem to be the problem. If anyone has a solution let me know as well.

I have a 2002 and it happened to me and my mechanic found out that the relay for the accelerator wire is too short and the gas pedal cable sometimes push this connection and it makes the car stall. The cadillac dealer diagnostics for $78.00 did show the part and the problem. So go and get this done they should tell you what it is. if no help I will try to fing the part number and you can ask them to look at that area.

To " Recorder"I can only tell you that I also had the same problem which turned out to be in the wiring that goes from the door to the B pillar, seems that the wiring gets stretched and then either almost breaks or completly breaks, hence sometimes the windows will work with the door shut ( not fully broken wire ) or will cease to work altogether ( fully broken wire ) as a note, one side on mine broke within the rubber covering between the door and pillar and the other side actually broke inside the door pillar ( which was harder to repair). In your case I suggest that you look either side of the rubber cover and if its not failed there then splice the cover to see if it has broken inside.
Hope you find that its the problem.

I purchased this car recently as a used car. It was driven by an older guy who took good care of it. The problem that I am having is oil consumption. I have only driven the car 1000 miles since I got it. It had 65,000 when I bought it. Is this common with the Northstar engine of that generation? If so, what causes it?
