Switch, Headlamp: Description

The headlight switch is located on the instrument panel, molded into the steering column opening cover to the left of the steering column. Several different switches are used, depending upon optional equipment requirements. The standard switch features a three-position rotary knob for exterior lighting control. An optional switch has a fourth position added to the rotary knob for automatic headlights 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 back of the switch housing has an integral connector receptacle 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 backlighting for visibility at night, but is not serviceable.

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