2004 Oldsmobile Bravada. My driver seat without memory or heat will not move in any direction. No noise from switch, no noise from motors, nothing. Also noted the seat belt warning does not work on driver's seat either. Is this indicative of a failed DSM? 2004 Olds Bravada, that I just purchased thinking it would be an easy fix. Tried the screwdriver pry and hammer tricks, no joy. About to pull the seat out, but thought I would ask the forum for wisdom before doing that. Thanks!
