DIC AND COMPASS PROBLEMS
HI, I have a 90' Bonneville SSE and my DIC and Compass only come on half the time, and when they do come on they only come on at half brightness. I have tried all fuses under the dash, and the fuses behind the glove compartment. what else could it possibly be?
Thanks,
Devon

It sounds like you have a problem with the circuitry that dims the VF displays, or the wiring to or from it. When your headlamps are on, those displays should be at half brightness.

Is there a relay for them? because they do dim when you turn on the headlamps even more, sometimes shuting them off completely... I would really like to get them working at full brightness.

everything dims properly except the climate control... the DIC and Compass do dim further, and when you turn the dial they go further, until they shut off...
but the strange thing is that they sometimes they work 100% perfect.

I know the 92-99s have a problem with those same displays. I'm not sure where the circuitry is for the VF displays in the 90. You need the wiring diagram from the factory service manual. On my car it is inside the instrument panel, which means the whole panel would have to be replaced. The climate control VF dimmer is actually inside the radio on 92-93 models.
But, on yours, I'm not sure. Wherever it is it sounds like the wiring to or from it, or the circuitry is going bad. Your headlamp dimmer switch and its wiring seem to be fine.

This is where I would send my instrument panel to be repaired. These guys do GM work. Possibly they can answer questions.
