My 08 Silverado LTZ seatback lumbar support popped and stopped moving recently. The motor still humms and everything else works. I suspect that something broke inside the seat. Anybody have any idea what it will take to fix it and what parts I will need?

Thanks,

Jeff

 

I have not seen it myself, but about a year ago I had a plate replaced in the seat which holds the entire lumbar system. It had cracked and the warranty fixed it.

I have within the past few weeks broken it once again as well, but haven't looked into fixing it again yet.
