2004 Pontiac Bonneville Electrical Problem

[Hermes3223]

I have a 2004 Pontiac Bonneville that runs great. My only problem is about a week ago my all my power locks and windows stopped working except for my front drivers side. I tried checking all my fuses under the back seat and could not find anything that had blown. Is there anything else I should/could check that could be the problem. Thanks for your help!

you could have a break in the wire harness that goes from the drivers side door to the body within the rubber tube. The door would have to be opened up to check the connections to the switch and then follow the circuit from the switch to the rest of the car.

I had a similar problem with my Bonneville SL 2002. Turned out that the wires were corroded due to water seepage and the grounding for the electrical system had become detached making it near impossible for the car to respond to remote or manual commands for locks and windows.

After exam by a competent electrical specialist, the water situation was (temporarily) resolved and partial rewiring with re-establishment of the ground connection returned normal function. The repair cost less than $200.00
