Normal Operation
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The driver seat control switch is supplied battery voltage on circuit SBB32 (VT/RD) and ground on circuit GD126 (BK/WH). When pressed, the seat control switch supplies voltage and ground to the appropriate power seat track or recliner motor to move the seat or backrest.
There are 3 power seat track motors that combine to move the seat cushion horizontally (forward/rearward) and vertically (front up/down and rear up/down). There is an additional motor in the recliner mechanism to pivot the seat backrest forward and rearward.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Seat control switch
- Seat track
- Seat recliner motor
