Fog Lamps
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The fog lamp switch is integral to the headlamp switch. When the fog lamp switch is engaged, voltage is supplied by the SJB to the fog lamp relay coil, which then energizes and routes voltage to the fog lamps. The fog lamps can be turned on when the ignition switch is in the RUN or START position, the parking lamps and/or low beam headlamps are on, and the high beam headlamps are off.
