Headlamp Switch: Description

The headlamp switch is located in the instrument panel. 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. 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). This switch also contains a rheostat for controlling the illumination level of the instrument cluster lamps.

The headlamp switch cannot be repaired and, if faulty or damaged, it must be replaced.
