Driver's Seat Sliding back and forth

[lowpost99]

I have a 01 NBS Tahoe with 6-way power seats. The driver's seat base has recently begun to slide ever so slightly forwards and backwards without the motor. The upper rail with the seat, is sliding along the lower stationary rail which is bolted to the floorboards of the truck, all on its own about an 1/4 of an inch. It's especially annoying when I come to a stop, and pull away from stops. Any ideas if there's an adjustment that I can make to correct this? The seat's lumbar adjustments also do not work any longer, but the motor just runs.

there is a kit you can buy off of ebay that has shims to put in the seat gear that fixes it, you have to pull the seat and take the gear apart and put the shim in and put it back together, cheap part but some labor involved I have 3 or 4 of those kits hiding somewhere I bought them and never put them in because I am tall usually keept the seat adjusted all the way back and then it doesn't move anyway.

What Wes said or gear stripped. Open up that seat to see why the motor runs but has no lumbar adjustment. More detail likely coming from other members.

Are these shims for the lumbar issue or the sliding seat rail issue? If I move the seat all the way back, it still slides fwd.

lumbar not working is probably a broke cable. had to replace that in mine. was not fun to get to.

Some good YouTube vids on that issue. Seat is fun to get out the first time don't mess with the airbag sensors under the carpet.

The seat's not all that difficult to remove. I'd probably disconnect the battery before pulling the airbag connectors. And don't let the external Torx mounting nuts scare you, you can use an appropriate deep metric or SAE socket that fits tightly. I think I used a 6-point socket when I pulled mine.
