Major Electrical or Tech Problem, I guess?????
Hi,
I have a really strange problem with my 2000 Bonneville SSEi. The auto windows, doorlocks, seat memory, tilt mirror memory, light in my console all just QUIT!! I can't roll down my windows or lock the doors, even with the fob. Then, the radio won't shut off. I have to manually turn it off when I get out of the car so it won't run the battery down. Has anyone had this happen to them and what is the problem.
Thanks for any input!

Thanks for your reply.
Yes, all the fuses have been checked. I have had it looked at and the Tech. thinks this is weird, too.
Any ideas would be so helpful. Could it be a short? If so, where and what.
Has this happened to anyone else?
Thanks,
Krys

I believe there is a relay that keeps all of those items switched on even after you shut off the car, until you open the door or until a certain time goes by. At least that is what mine does. So it sounds like maybe that relay may have a problem.

Check the BCM
Many of your symptoms sound very similar to the problems I had when my BCM failed on my 93. They called it a RAC back then, but I think the new term is Body Controller. I found a website that said it was common on the 93'*. Obviously, my 93 shop manual is no good on a 2000, but maybe someone who has one can help? The only test for mine was to make sure the connections were clean with no corrosion.

However, its sole job is to keep the accessories going after shutdown by providing an alternate power source, not to operate them in the first place while the car is running. The Body Controller in the newer Bonnes is a full-blown computer, as I understand it, and does things completely differently, including being in charge of those accessories at all times. So you're going to need some diagnostics relating to your year of car; I don't think how the '93s retained accessory power after shutdown is going to be relevant here.
On the other hand, your symptoms are so obvious and easy to describe that you could practically get a diagnosis over the phone from your Pontiac dealer. I do think the BCM is suspect here.
