Normal Operation
WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The seat control switch is supplied battery voltage on circuit 517 (BK/WH) and is supplied ground on circuit 57 (BK). The seat control switch applies battery voltage and ground directly to one of 3 bi-directional seat track motors, respectively, to move the seat. Toggling the seat control switch to the opposite position reverses the voltage polarity applied to the respective seat motor and moves the seat in the opposite direction.
This pinpoint test is intended to diagnose the following:
- Circuit breaker
- Wiring, terminals or connectors
- Seat control switch
- Seat track (motor assembly)
