Hi, My name is***** will try to help. Please post what you have for fault codes.
This sounds like either a ground issue backfeeding or a problem with the body control module. Check all your grounds and wiring connections and for damaged/corroded connector pins. If okay I would have the body control module reflashed/updated and tested. It sounds like a faulty module but I would make sure the grounds and wiring test good first. Let me know
Hi Manny, Did you get this resolved?
