Yeah, the same thing happened to me around the time I first got the car, but after a while, the seat wouldn't go up or down anymore. I even got stuck up all the way up one time, and I couldn't get it back down till a couple of days later after I banged the hell out of the seat track. I went to Ford to see if they could tell me what the problem was, and they said that some part that controls the movement on the seat track had burned out. The only option was to replace the whole track for $300. Yeah right I'm spending that much on that crap. So instead, I went to a salvage yard and just took off manual seat track another Mustang seat. It costed me $30, and I don't have to worry about the power seats anymore. On the plus side, you also save a couple of pounds of weight. Belive me, that power seat track is heavy. Takes about 45 min to replace, and you still have the connection for the lumbar. If you still want the power seat, just look for the power seat track, and replace it.
