Dimmer Switch

WARNING: This page is about a different car, the 2013 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The dimmer switch is a momentary contact switch that is integral to the headlamp switch. The headlamp switch is hardwired to the BCM  . When the dimmer switch is pressed up or down, the switch completes a ground circuit to the BCM  corresponding to the desired action (increase or decrease illumination brightness).
