None of my dash lights work, but all the gauges do and everything else is fine. No flickering or anything and the high/low beam switch works fine. I'm not far from cracking the dash and diving in. I know to check the grounds back there, but I was wondering if there is a low voltage regulator/circuit board in the dash headlight dimmer switch. I don't know if that is where they are on these rigs (81 wag), or somewhere else. I need to replace the headlight switch anyhow so I'm hoping to bust two knuckles for the price of one.
