'99 GC - Dash won't dim

Need a little more information. Tell me if I am correct. The dash lights come on, but will not dim? When you rotate the knob counter-clockwise, the interior light comes on, but if you rotate clock-wise, the interior light goes off, but will not dim the dash lights?

If the above is true, then it sounds like the dimmer has died.

The dash lights come on with the lights but do not dim w/ the adj of the knob. The knob has no affect on dash or interior lights.

Probably a bad switch in the knob. Not sure if it's a dealer item or a junkyard item.

Isn't there a second dedicated dash dimmer switch?

I have a '93 that has a separate switch for the headlights/park lights, and the interior lights. To dim the dash lights, and turn on the interior, you move the second switch. Mine is located on the left side of the dash, below the light switch. I'm not used to having a switch on the dash in a vehicle, so just about every time I drive at night, I first turn on the windshield wipers.... Hippie

My 2000 also has it on the headlight switch. Clockwise to time, counter clockwise to brighten. Counter clockwise past the 'click' to turn on interior lights.

I would next suspect the stereo wiring.... I see folks that connect up the wrong wire to dash lights thinking the radio lights will come on with the headlight switch. This can be a power line for the power antenna or remote not a light wire like the old ones had.

You may be on to something, Mike. The aftermarket stereo has been 'hotwired" - it can be operational with the car turned off.....
