Description






DESCRIPTION







The headlamp switch (1) is located on the instrument panel, to the left of the steering column. Two different switches are used. The standard switch features a three-position rotary knob (4) for exterior lighting control, a thumbwheel (2) for panel lamps dimming and interior lighting control, and a momentary push button (3) for cargo lamp control. An optional switch has a momentary PUSH function added to the rotary knob for front fog lamp control.

Each of these switches is constructed of molded plastic. The rotary knob is molded plastic and knurled around its circumference to ease operator control. The thumbwheel is also plastic and knurled. On vehicles with optional fog lamps the rotary knob also has the text PUSH and an International Control and Display Symbol icon for Front Fog Light applied to it. The cargo lamp push button is plastic with a smooth finish and the text CARGO applied to it. The switch face plate is also labeled with graphics and icons to clearly identify the many functions of the rotary knob and thumbwheel.

Three screws secure the switch to the back of the cluster bezel through integral mounting flanges that are molded to each side of the switch housing. 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 incandescent bulb 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.
