Question about 1999 GMC Jimmy

1 Answer

Drivers seat lumbar.

I was applying the parking break and the lumbar support seemed to give way, i heard a ratcheting kind of noise and now the lumbar has no support. It feels like the support bar is moving but not far enough forward to give the needed support. I also would love if someone knew how to take the seat apart could explain how to get to the lumbar system. THANKS

Lumbar control does not work in 2001 Dodge Durango. The seat works fine otherwise


For the years around 2001 with those seats (00-03 I believe) they have a plastic lumbar adjuster in the back of the seat. I can't seem to find anyone who sells it even the dealer. All I could suggest is try and get a crappy used seat (perferably a passenger seat because they are used less) and swap it out or just get another drivers seat if you don't want to hassle with it. It's not that easy to change. I've tried to repair mine a few times. It kept failing. I'm going to try it again and this time move the stress point to a different location so this hopefully won't happen again.
