Drivers side power seat won't go up or down but can hear motor running when hitting switch. The seat moves in every other direction. Any ideas? Thanks for any ideas.

 

Common issue is the PLASTIC gear on the motor to strip out. Replacement of the track is normally what is done although it is very costly.

Someone just recently over on DT found replacement motors and gears though. Might wanna check over there
