Principles of Operation - Power Seats Without Memory
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The 6-way power seat feature moves the seat in 6 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 and down independently. The power seat feature operates independent of the position of the ignition.
The power seat motors are hardwired to the seat control switch. The circuits are normally at ground through the seat control switch. An individual circuit is switched to power when a specific adjustment position is selected.
