Hello Guys, I just picked up a 2000 Bonneville ssei yesterday with 111K. It was a good deal I jumped on it. It has a funky electrical problem. It seems to be a common one but I researched on here but still can't understand a fix for it. All 3 passenger door windows and locks are not working, no light on passenger door lock switch and the driver power seat and heat element are not working, the guy b4 me said they all went out at the same time. I don't know if this is BS or not. I also don’t know if their even related. I've checked all the fuses, but B4 I get deep in to it I figured I'd ask and maybe I save some time, I work at a Pontiac GMC dealer, I could ask a Tech that may know. but I don’t want to wait till Monday to fix this HAHA! Cause after this I got some other work to do on it (intake gasket, flush, Motor mount, ECT. I’m a ASE Certified Auto student so I can handle electrical tests and part replacement. Just let me know where and what! Thanks so much for the help, Guys! I can’t wait to get her on the road!-Rick

Sounds like the Driver'* Door Module has gone bad, I would have them check it with a Tech II

I agree on the module.

Either that or it'* related to the wires going into the drivers door. Sometimes they can pinch and break at the rubber door boot.

I swaped the driver door switch mod. out with a friends 2000 ssei and still the same results. I allready investigated the wires between the door and body in the rubber boot, none where pinched, or cut, plug was in good cont. I'm thinking it may be a bad BCM. When I get to work monday I'm gona run a tech ll on it see if there are any related coads for a BCM read error. See if I cant reprogram it if not get a new one. Untill that I got to get my Drivers seat out. I got to take it all apart to get the back 2 bolts out because the seat track is in the way. Dang! Anyone seem to agree? Thanks!!!!

I'm not exactly sure where the BCM is but I would think under the dash and not where the seat would get in the way, correct me if I'm wrong

BCM is located front right of engine compartment underneath the fuse panel there not a serviceable unit without a tech II

Under the fuse block? can you post a pic Saw? I just don't remember seeing it and I'm 2100 miles from my car

it'* raining here right now but i will try and get ya one

number 12 in the pic is the BCM
