Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello! I apologize that there hasn't been anyone to help you yet. What exactly is the seat doing/not doing?
If they've already replaced the door module and it's still having issues, then it sound like there's a wiring issue, they share a common ground at the base of the "B" pillar, plus the wires under the seat could be broken. All that being said, if a dealer is working on your vehicle, and they told you the module would fix your problems and it didn't, then you're not responsible for their misdiagnosis. Get in touch with the service manager and if that don't help go over his head, no shop can throw parts at a vehicle at the customer's expense, so don't let them do it to you.
