Headlamp Switch: Description and Operation

The headlamp switch is a multi-position switch.
^ The positions include OFF, PARK, and HEAD.
^ With the headlamp switch in the PARK position (first detent), a signal is supplied to the LCM which powers the front parking lamps, the tail lamps, the side marker lamps, and the license lamp.
^ With the headlamp switch in the HEAD position, power is supplied to the headlamps through the LCM and the multifunction switch.
^ The panel dim switch (part of the headlamp switch) is located above the headlamp switch. The panel dim switch operates only with the parking lamps or headlamps on.
^ When the panel dim switch is held in the up position, the instrument panel lighting will progressively brighten.
^ When the panel dim switch is held in the down position, the instrument panel lighting will progressively dim.
