Check to see if something is caught up in the slide areas of the seat track.
There would be no need to grease anything.
Let me know if there is or isnt something in the way down there.

if you look , you'd have seen them.
but id bet it not the bolts. but do look
what you do is look at the track.
the track has 2 parts. bottom and top
if you wiggle the seat and the :
bottom wiggles with top , the base is loose.
if the top and bottom tracks , only move there, the track is bad.
there is no visual play at track juncture. so..... if there is, its bad.
if the base and track dont move the seat frame is cracked.
sounds hard, no,
its a 10 second job, you look and see what is loose.

now my wild useless guess.
the someone removed the seat, and its on back on track.
or as my fat boss did, broke the seat frame.

I found this on ebay.. some pretty detailed pics:

Not really a cheap way to fix it. You have a motor and cables that turn to move the seat. The motor and cables would need to be removed to allow the seat to move, then there would be nothing to keep the seat in place unless you put the motor back.
A manual seat uses a latch and slotted track to move the seat and lock in place.

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

I would buy one from the junk yard and replace it as its very hard to put back on track as it will keep coming out again and again.

Check the inside of the track for an obstruction. You will need to move the seat all of the way forward, but you should be able to see if there is something obstructing it and keeping it from moving. The dead give away is if the seat moves up after you move it all of the way back, there is something in the seat track.

You might have a problem with the wiring under the seat. The best thing to do is to reach under the seat and move some of the wires away from the track that the seat moves along. Most likely there is a short to ground because the wires are rubbing against the seat track as it is moved back and forth. You need to grab a flashlight and look under the seat for wires touching the seat tracks. When you find them, you can most likely use some electrical tape to wrap the exposed wires and keep those wires from touching each other and that area from touching the seat track. Make sure you route the wires away from the seat track tight enough to the seat's underside, but loose enough to allow the wires to move with the seat as it travels the full length of its track. The fuse for the seat has probably blown so you would need to replace the power seat fuse AFTER you wrap and reroute the wires to prevent blowing the new fuse.

Hope this helps!

If it is blowing the heated seat fuse. Pull the drivers left side seat trim back to remove the seat switch. about 2-3 inches behind the switch you will likely find the wiring is rubbing on the seat track. Wrap with electrical tape and put a piece of rubber hose over it so it doesn't rub thru again. I do think this will fix you problem. I have repaired this problem many times.
Hope this helps
