Headlamp Switch - Description

DESCRIPTION





The headlamp switch (1) is located on the instrument panel, in a cylinder-like mounting hole molded into the headlamp switch bezel to the left of the steering column. Several different switches are used, depending upon equipment and market requirements. The standard switch features a three-position rotary knob (4) for exterior lighting control. An optional switch has a fourth position added to the rotary knob for automatic headlamps and a momentary PUSH function added to the rotary knob for front fog lamp control.

Each of these switches is constructed of molded plastic. On vehicles with optional fog lamps the rotary knob also has the International Control and Display Symbol icon for Front Fog Light applied to it. The switch face plate is also labeled with graphics and icons to clearly identify the many functions of the rotary knob.

The switch housing is secured within the mounting hole of the instrument panel bezel by two spring loaded, pivoting pawl-like retainers (2), one near the bottom and another near the top. These pawls can be retracted for removal of the switch from the face of the instrument panel using a specific rotary knob actuation sequence. Headlamp Switch - Removal.

The back of the switch housing has an integral connector receptacle (3) containing terminal pins that connect the switch to the vehicle electrical system through a dedicated take out and connector of the instrument panel wire harness. A panel dimmer controlled Light Emitting Diode (LED) unit soldered to the circuit board within the switch provides back lighting for visibility at night, but is not serviceable.

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