Fog Lamps
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
The fog lamps are controlled by the headlamp switch. The switch toggles the fog lamps between on and off. When activated, the switch sends a signal to the SJB. The SJB then activates the fog lamp relay, providing power to the fog lamps. The fog lamps will not illuminate when the high beam headlamps are on.
