There are two steel rollers with an O ring around it's center on each bottom rail somtimes these rollers get jammed when the seat is moved to far forward , spray the bottom rails with WD before you smack them ,you should be able to tilt the seat half in the car with the electric connected and the tap the top rail that moves while a friend hits the back button, don't hold the button down or you'll blow a fuse. (might be a good idea to check that fuse before you start)........
