Please help, electrical problems.
[align=left]
Thanks in advance to anyone who adds their 2 cents. I have a 99 cadillac seville sts with 99k on it. I've never had any problems before but recently the electronics have gotten all messed up. When I was driving yesterday the service engine light came on, then my instrument dash got all screwy.
1) the rpm and speedometer stopped working.
2) the entire lights on my dash would flick on and off while I was driving
3) the rpm and speedometer would go from working to being turned off back and forth.
4) finally when I was almost home my car SHUT OFF while i was driving, basicaly the power went out and I couldn't accelerate anymore, all the lights went out on the dash and I pulled over. Eventually I was able to restart my car and drive home but it took a few tries, the funny thing is I dont think it's my battery bc the battery low indicator never came on.
Can someone please give me some advice? I don't think it's a battery so it might be a blown fuse or alternator?
thanks![/align]

RE: Please help, electrical problems.
Yeah, I am getting screwing readings from my OBD as well. Service the Theft system most often then it will go away and not return for a while. I am concerned because when I asked the garage to check my "non heating" heated seats they said the grid was screwed up. When it gets warmer I will be tracing the wires to the heated seats to see what's up with the grid but the notices give me some concern for the electronics. I will say the stability control isn't effected and it is cool as all heck, I have purposesfully over turned thecar a few times this winter (purposesfully for full effect) and the stability kicks right in and "rights" me pretty well. This is my first winter with the car and stability control so I find it very comforting that it works.

i had a very similar problem with my 99sts. it turned out to be the contacts in the ignition switch harness plug. this can be fixed by checking/cleaning that harness behindkey switch. will need to remove radio/ac controls to reach behind dash
