w108 250s dash lights

[Labadie250s]

So my dash lights wont work? My brights, turn signal, and brake lights all work. so it just the gauges. I checked the bulbs and fuses. What am I missing?

If it's like my old 67 250S was, there's a dimmer rheostat below the speedometer. I don't remember which side below (I think it was left), but turn it all the clockwise for brightest, and all the counter clockwise for dim/off.

turn the rheostat knob back and forth quickly several times to free corrosion from its resistor coil.

Thanks for the advice. I was wondering what that knob was for. However I had no such luck with it turning the dash lights on. Could the rheostat be broken? would that make sense?

The contacts corrode over time. Turn the knob back and forth for a long while, like a few hundred times. Search 'jumper' in this forum's archives for another solution.
