Anybody know what would cause a power seat to not move front-to-back on a '98 F150 Super Cab? The tilt and the up/down functions work fine, but the seat is stuck all the way back and won't move forward. I can hear the seat motor click, but nothing happens.

 

check for something jamming the gears or the tracks on the tracks. The other possibility would be the motor going out. That motor is going to be different from the tilt/up/down motor.
