I have a 2000 Bonneville ssei and I suddenly have lost all power options in the passenger door. It was working fine one minute and then just quit working the next. I can't put my window down, power locks don't work and the lights on the switches flicker on and off. I'm just wondering if anyone else has had this problem and how they fixed it. Thanks in advance.

There is a drivers door module that goes out and when it does, it replicates what you are experiencing.

Another problem that can cause similiar symptoms is a bad ground.

If you find someone who has a Tech II scanner, they can pinpoint the problem area to a particular module, ground, communication bus and it will save you oodles of time for troubleshooting.

Oldsman had similar issues with dead door disease. He found a bad passenger door module and a bad lock switch IIRC. You do really need a tech 2 to diagnose properly.
