Power Seat Operation - Passenger and Driver (Without Memory)
WARNING: This page is about a different car, the 2021 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The seat control switches contain normally closed contacts which are grounded. An individual circuit is switched to voltage when a specific adjustment position is selected. The seat control switches are hard-wired directly to the applicable seat motors. The motor direction is determined by the polarity of voltage supplied from the seat control switch.
