90 K1500 Dash lights

    I just picked up a 90 K1500 v6 ext cab/short box. When I turn the head lights on the dash lights don't come on and the radio and heater control lights shut off. Any suggestions where I should look for problems?

    Need to replace the Dash dimmer thumbwheel portion of the headlamp switch assembly.

    I think they are the same as 1994 K1500.

    That happened to me...

    Did the replacement dimmer work? I have the same issue on a '94 C1500. I disassembled the dimmer and it appears to be working, but still no lights.
