Principles of Operation - Power Seats Without Memory: Notes
WARNING: This page is about a different car, the 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
The six-way power seat feature moves the seat in six possible directions: the base of the seat can be moved forward or backward and the front and back of the base cushion can be moved up or down independent of the position of the ignition.
