Driver seat wont move back

look in the track that the seat moves on and make sure nothing is in its way

you may have to take seat out & relliy look in the seat tracks real good i had one that had a penny in it that i could not see

I am working on a replacement motor that will come with a new gear/shaft on it. I have one of my setups in the car right now and have the parts for another one ordered. I hope to make a video of the repair in a couple weeks when the parts show up. Still uses plastic gears, but these are larger, more durable gears and the swap is fairly straight forward with just a few modifications.

The power seat in the truck has 3 motors, one of them is not working, the most common cause of this is the power seat switch is defective, it is often the forward and reverse seat positioning switch that fails because it is the one that is most used. If the switch checks ok then you will need to replace the the power seat track assembly, Ford does not sell any parts for the track, it is only available as one complete unit, I know this because i retired form a Ford dealer. Please rate my help for Fixya. Thanks

If motor is running, but seat is not moving you probably have a jammed seat track.

gear in motor/transmission stripped,had one do that one time,had a penny stuck in the track

possible junk in track clean it then see if it works

check for penny or dime in track

Ck for debri or other objwcts in way of tracks Does it try to move? If so, there is an obstruction, If not trying or no sound when switch is moved, could very well be a fuse or the forward limit switch is being affected by excess forward travel. Move the switch yo back and without kinda help it. if it's trying.

Go under the seat and check both slide tracks for anything jamming it up...I've removed gloves, socks, candy boxes etc from tracks. Also if its not a power seat, check that when you move the release lever it is connected by a stiff wire to the opposite side. That wire releases the right side track. If broken or stretched, it wont.
