Have a intermittent problem with the driver information panel. It lights up like a x-mas tree and door open alarm starts dinging away. Sometimes will re-calibrate itself to normal. Sometimes it will re-calibrate by shutting off car and re-starting. Will do this on cold start or warm start. Also has happened cruising down the road or flying down the highway. A mechanic thinks it might be the body control module. Is this the place to start to rid this irritant problem.

What year is your car? Depending on the year, you may want to check the ground bus under the front doors for corrosion.

1997 Bonneville SSE

Give this a look. https://www.gmforum.com/t278980/ It might help.

Thanks for the help. I'll try the ground bus. Just wish it would warm up a little here in Mpls. Had snow last night and more forecast for Monday. Too early for winter. The ground bus looks easy enough to tackle. The car is in the garage more than on the road. Mainly drive a 2001 S10 because the Bonnie is such a luxury car to us.

Glad I found the Bonneville forum online. Anything is better then mechanic troubleshooting charges and repairs that don't always solve the problem. I can fix most repairs. Figuring out the fix is the hard part.
Thanks a lot for the advice!!!!!!!!!!!!!!!!!!

We try to cover everything we can in write ups. Take a look at the tech info area, if you don't see it there, just ask. I'll try to make one up if I can.

Well, I cleaned the ground buses but they were really clean and dry already. It did not solve the problem of the driver info panel lighting up to shows all the doors and hoods open, etc... Shut off the car and re-start and the panel reconfigured to normal. The ground bus areas were dry and not all rusty or crusty. Car is in great shape considering it is 12 years old. Any other ideas would be great appreciated.
Thanks for your great help so far !!!
