Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if it is the window, locks, and mirrors, or do the seat functions not work either?
Thank you. If it is just the door functions then most of the time it is caused by a break in the wiring going from the body into the door. Where the door pivots the wires tend to break over time from the constant bending. It can also be a connection issue. If you have a voltage meter I can run you through some tests once you inspect for broken wires in the jam entry.
Sounds good. I will look for your response then.
That is fine. Thanks for the update.
Thanks for getting back with me. It is probably the driver door module then. It is the module that has all of the door switches connected to it. Do you have a voltage meter to run some tests?
I will send over some tests that you can do.
Sorry for the delay. Your questions seemed to drop from my board and I could not find it. I did look a little closer at the schematic for this and it seems like the body control module is the problem. Did you check the TBC BATT fuse under the hood?
If the fuse is fine also check and see if it has voltage. If it does then check the connections on the body control module which is located udner the driver side of the dash on the steering column.
