sounds almost like a loose ground somewhere. I would find out where all the grounds are and unbolt clean and put them back on then spray some of those protectents that are availible for electric grounds.

dmathews3, thank you for your response!!! my 1st thoughts on this situation was grounds, and as i stated they were checked. however, knowing the wrench that worked it, he said he found one that was loose, (frt pass side) and tightened, though i am not sure if he continued to look at all....so a call has been made to the dealership to request the sheet he had of grounds. i'll check them myself. from what i remember there is 12, to 15 grounds on this vehicle. again, thanks , and i'll keep you posted. rdrags

I have a 07 STS and so far so good. Motorhome is in hibernation here in Mich. and no current problems except to dang cold. I do need to get out there and start it up and let it run for a while.

I had the same thing happen on my 1993 STS. The problem was a pinched wire under the drivers seat causing one of the big circuit breakers in the panel on the drivers side wheel well under the hood to keep resetting. Check to make sure all those wires are free and not pinched.

Thank You for that....Ya know when I purchased the car, the drv. heat seat was and still is inop..... don't care too much for the heat so never had it fixed.......???? I still haven't found the exact problem, though a disconnect of the negative battery cable, (under rear seat) re sets everything and all electrics stay going for a good while. Its funny you should mention that though, that was the only thing I could fault the car for, other than the electric-dash problem. who found the problem for you?

The mechanic at Al Piemonte Cadillac in East Dundee, which has closed and moved to St. Charles, IL. He diagnosed a clicking when I turned right as a weak spring on the starter causing the gear to hit the flywheel ring gear when I turned. Other mechanics said it was the CV joint and I should have that replaced. Went through 3 starters before I go a good one.

I am having the same problem. Can you tell me did you solve your problem and if you did what did you do to correct it. The problem I am encountering is the gas guage going from full to empty, radio comes on and off, the windows and door locks, security light and abs is on steady etc, replaced ignition switch. HELP, HELP, HELP!!!!!!!!Thanks for your time and cooperation.
