Panel Illumination Control Module: Description and Operation

The intensity of the instrument panel and instrument panel cluster assembly lamps are controlled by an illumination controller located on the left side of the instrument panel. Rotating the illumination controller clockwise will brighten the instrument panel cluster assembly, radio display, cluster bezel switches (rear defogger, rear wiper and rear washer, if equipped), and heater control unit. Rotating the illumination controller counter clockwise will dim the above mentioned lamps. The parking lamps or headlamps must be activated for the instrument panel and instrument panel cluster assembly lamps to be illuminated.
