Yeah, when a car gets bent a bit, some chassis grounds get moved around. When I chase electrical gremlins on a car after a fender bender, I usually check out all the grounds to chassis in that area. Tighten them down since they move under impact. A harness will either snap or bend. But chasing a ground choke point is difficult.

Try to follow the ground choke points that share the common radio and door locks. They may be on left kick pillar.

Driver door switch ground is confirmed at G639 left kick panel, radio ground is G610 I think behind center console. Anyway, power is not at all on same B+ line.

You could give all those components a proper ground to each and they would work regardless, but tracing the B+, should be easy with those wiring I gave up.

Hope you liked my upgrade from white on black I used to post.

;)

Hope you keep busy, it is important to do so.

Hey Nick....I checked the grounds and they are ok....still no door locks or stereo....can you send me a diagram of the fuse box under the hood...I don't have a diagram of what the fuses are..I keep blowing one of them and a little smoke from under the drivers seat from the metal box or module (not sure what it is)....i guess when they did they body work they replaced the drivers door from a donor car...Not sure but he thinks they used they wiring harness and module from the donor car....and the original one is gone....I have had a problem awhile back from another car...don't remember what it was,but things wouldn't work with the donor module had to use the one from the car originally....maybe it can't see this module....Jim

.Not sure but he thinks they used they wiring harness and module from the donor car....and the original one is gone....I have had a problem awhile back from another car...don't remember what it was,but things wouldn't work with the donor module had to use the one from the car originally....maybe it can't see this module....Jim
This would explain alot.

But not the radio.

I will check tommorow on a co workers car, he has almost same model car. I will plug in my scanner to see if there is a driver door module reset/reflash available.
