Is there a rheostat for the dash lights?

Yes.
It's on the horizontal surface under the dash pod - the surface that faces your knees. A knurled wheel .
It is I think on a LHD car on the same side as the headlight/indicator stalk. There is another similar rheostat wheel on the other side (under the wiper stalk ) that adjusts the intermitttent wiper frequency.
Most hopeful scenario is that in the gymnastics involved in fitting the radio you just inadvertantly dialled back the brightness with a knee or misplaced elbow/**** etc.

Fred if you can get your hands on an owners manual it will detail all of the switches on the pod

This is a good point, the contacts on the controls can eventually corrode and cause a poor contact and intermittent light or no light. I noticed this on my S4 as well.
Moving the wheel slowly every 6 months should help keep it clean.

Now that you've discovered it, reach in and disconnect the two wires that go to it. Make a small jumper. Attach the two ends together. Enjoy brighter dash lighting.

The dash lights are brightest when the lights are off, during daylight - turning on the lights includes the rheostat in the circuit and the dash gets a little dimmer. Bypassing it should mean that with lights on, the dash is as bright as it is with lights off.

At least on my 89 S4, the rheostat still dims the lights from full brightness even at its lowest resistance position.

my dash lights dont go on now. the dimmer never worked on the new racer ,, but for night driving, I would like to have the dash lights. anyone know where to start? fuses are all good for what might be considered in the circuit.
thanks,

Mark, You might just get a test light and check for juice before you rip it apart, but that thing was the source of my problem, and I believe many others as well.
