Hi guys, glad to get such a great amount of responses!
(we must love our contours eh?)
The dimmer switch itself has a light emiting diode. It hasn't worked for a few years now if I recall correctly. It went out about the same time as the clock light did, within a few weeks. Strange but true. :-)
The dimmer switch has three terminals.
1) power.
2) return ground for the dash lights.
3) guessing - return ground for diode? Based on my observations when I took the switch appart.
The turn signals, emergency indicators and other dash lights work.
The actual illumination of the guages and dash backlight do not.
