Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. I have come across similar issues many times. Most of the time it is caused the body control module failing. I have also seen quite a few issues with the wiring that goes into the door breaking or chaffing and causing a short. Both of these are common. Did you plan on fixing this yourself?
You can install a new body control module, but it does need to be reprogrammed with a factory scan tool. If not then the modules will not communicate with one another.
Any shop that has the right scan tool to do it is able to. Typically a TECH II scanner is needed.
