I just got my 68 Coronet back on the road and realized I never tackled a problem that occured this summer: I have no dash lights. I traced the problem to the dimmer switch. The main light switch sends power to the dimmer switch, but I have no power from the dimmer switch at the instr light fuse. Is the dimmer going bad a common thing? Or is there something I could be overlooking. If it helps, the console/dome lights work, but the dimmer doesn't dim them (although I dunno if it's supposed to).
