Note, Im in the end of a restoration with this 92, and the headliner and dome light is not in yet, could the open circuit of m=not having the dome light assemble in place be the cause?
I pulled apart the instrument cluster to inspect the dimmer switch. It seamed operational, and it still can turn on the dome light. the two coils are slightly oxidized, i guess there could be a small break in the one of the two coils that i cant see. Do you think it could be the heaDLIGHT SWITCH?, ALTHOUGH THE HEADLIGHT SWITCH TURNS ON THE THE HEADLIGHTS AND DRIVIng lights , no problem.
