GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello, my name is***** is a feature that is programmed into the body control module. You either have a wiring issue still from the lock cylinder to the BCM or it is more likely that the programming in the BCM was not done correctly. I would take it back and ask them to program it correctly.
With used parts it is hard to say if it is even configured to do this. All that can be done is to access the BCM with a factory scan tool to see if that is an option and then turn it on. It depends on the parts that were installed.
The master cylinder would not have anything to do with it. The lock cylinder where the key gets inserted would. If that is new then this is a programming issue.
Even as a GM part it has to be properly programmed and configured.
No problem. If you need anything else please let me know. Please also rate my service when you have time. Thank you and have a great night.
