Headlamp Switch: Description and Operation
The headlamp switch is located in the instrument panel, outboard of the steering column. It closes a path to ground for the Central Timer Module (CTM)
when the park or head lamps are ON and the driver door ajar switch is closed (driver door is open). The headlamp switch opens the ground path when
the headlamp switch is turned OFF. The ground path is also opened when the driver door ajar switch is open (driver door is closed).
The headlamp switch controls the parking lamps and the headlamps. A separate switch in the module controls the interior lamps, and instrument cluster
illumination. This switch also contains a rheostat for controlling the illumination level of the instrument cluster lamps.
The headlamp switch has an OFF position, a parking lamp position, and a headlamp ON position. High beams are controlled by the multifunction switch
on the steering column. The headlamp switch cannot be repaired. It must be replaced.
