Driver seat adjustment issue

[emillika]

My wife's 2004 H2 is having an issue with the driver seat adjustability. The seat moves up/down tilts forward/back thru the complete range of expected motion. However, it will only move forward/reverse about an inch or so in each direction.

-seat heaters work fine
-passenger seat works fine in all regards
-checked for any obvious obstructions near the seat track
-blew compressed air along the track

I have searched here and online but no luck yet. Removed several fuses to see if the seat control module would "release" it's memory and also disconnected the seat control module under the driver seat for 10 minutes but no luck so far.

Any idea's on what else I can check?

Thanks.
