driver power seating on 1999 Mercury Sable

The power seating in the driver's seat isn't working and the seat is all the way back. What part should I be looking for when going to Auto Repair shops?

Its a fuse...

It could just be a fuse. Fuse #4 in the power distribution box, front center of vehicle under hood. Hopefully this is all that's wrong with it. I only wish the seat not working would be all that's wrong with our 99 Sable. Haven't even had it a year and it has been a nightmare already.
Look for a blown fuse to drivers seat. Also, the wiring for the seat runs under the carpet and sometimes corrodes from salt and water. Also could be just the rails rusted.
