This dash switch handles multiple functions from one panel-mounted control — switching the headlights and fog lamps and adjusting instrument-panel dimming. If a worn or failed original switch is the cause of lights that won't respond, dimming that won't adjust, or intermittent operation, this replaces it. The part is listed under Fog Light Switch, Headlight Switch, and Instrument Panel Dimmer Switch names.
