I recently bought a 1999 S10 Blazer the drivers side seat when moving forward the right side does not move the seat goes cockeyed. Everything else works auto parts store does not have a breakdown on the seat. Could anyone enlighten me. Thanks
Here is a video that does a decent job of explaining how automatic/powered seats work.
It's a long video and if you already have your seat removed, you could advance the video to about 13 minutes and 27 seconds.
At 25 minutes he pulls out the drive gear. You either have something stuck/binding that drive gear from moving in the seat track or the cable that turns that drive gear is broken.
