My 6 way seat isn't fully working the side to side lumbar pillars no longer move in and out. When the 4 way dial is pressed, the motor whines, but no movement is happening. The forward and backwards lumbars work fine. I'm assuming there must be some broken gears or a cable that is broken. Any ideas on how to get it fixed again?

It depends on the model year. I know from experience that the BCM and DDM had updates to them which cured a whole host of seat related issues.

Aside from that it looks like the seat needs to come out to inspect.

It from a 2001 LT Tahoe. Have any reference information such as an exploded view of the seat? Thanks.
