Hi All:

I have a 69 and when I rotate the headlight switch knob the dash lights do not dim. If I turn it all the way CCW to just before I turn on the dome light, the gauge lights are on, but if I turn it to the right any amount the dash lights go off.

Is the switch worn out or is there somewhere else I should look to fix the problem so I have dim-able dash lights?

Thanks for the help.

You got..... it bad rheostat on switch. Replace switch with a good quality replacement(read NAPA)
A switch with High resistance can cause wiring to fail especially on cars with older sub par wiring insulation (like all GM A bodies)
