Ok so Pete, my 7 foot tall 16 year old, bought his first car, an '81 Mercedes 300 S-class Turbo-Diesel today... This evening he determines that the dash lights don't work. I go to the Mercedes group online and ask "Where are the dash panel light controls This is what i am told like 3 seconds later:
"It is operated by turning the left knob/button on the instrument cluster. The rheostat is frequently burnt out or corroded."
followed by:
"A simple jumper wire is the most common fix. Even the brightest setting is too dim for most people."
Suddenly I am at home with his purchase...
It kind of looks like a four door big brother to the '79 RBB... except it is (shudder) Butter Cream Yellow
