Seat won't raise/lower

I have a 98 M Roadster and the driver seat won't raise or lower. I hear what sounds like the switch working, but the gears don't seem to work....or so I think.

Thouhts/suggestions?

Upon further review, the threaded "bolt" seems to be frozen in place...will Limey have to take the seat off for repair

rofl Satch - I didn't have any idea but I didn't try that hard either!

Damn you auto-correct! Lol. Meant, will likely have to take seat off.....

Do you hear the raise/lower motor run when you push the button? I had a similar problem on my 98 M3 and it turned out to be a cracked nylon gear in the mechanism.

I actually got it fixed...the motor was working and the screw that is in there was just stuck in place....works perfectly now!
