Instrument Illumination

OPERATION
When the Headlamp Switch is in the "PARK" or "HEAD" Position, voltage is applied to all of the illumination bulbs and circuits in the components. As the Instrument Panel Dimmer Switch is moved from from the "DARKER" to "BRIGHTER" position the Timer Module receives this information. The Timer Module will control the brightness of the illumination by providing ground to the bulbs.

The only components that the illumination cannot be changed are the Rear Climate Control Panel and the Rear Radio Control.
