Dakota Quad Cab 4WD V6-3.9L VIN X (2001)
Headlamp Switch: Description and Operation
The headlamp switch is located on the instrument panel. The headlamp switch controls the parking lamps, the headlamps, the interior lamps and the
instrument cluster illumination. The headlamp switch also contains a rheostat for controlling the illumination level of the instrument cluster lamps.
The headlamp switch 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 cannot be repaired and, if faulty or damaged, it must be replaced. (Refer to LAMPS/LIGHTING - EXTERIOR' HEADLAMP
SWITCH - REMOVAL) for the service procedures.
