No Dash Lights
I just got a 78 1 ton and am fixin it up so I will be ready for this summer. The dash lights are not working. When I take a test light through the plug on the back side of the instrument panel nothing changes as I turn on and off the light switch. The blinkers, bright light and the seat belt light all work. I tested all the fuses and they are all good. There is a light between the light switch and wiper switch not real sure what turns it on but it does not turn on either. Any help to try and figure out what to look at would be great.

The headlight switch also activates the wiper light. . .
. . .I am having a similar problem, my headlights (including hi-beams), blinkers, and turn signal indicators all work but I don't have any guage illumination, no hi-beam indicator, no seatbelt or brake warning light and no wiper illumination either!
I also have good fuses, my printed circuit on the back of the instrument panel is good, I replaced all the bulbs and fuses and cleaned the circuit board with contact cleaner and still no dice. . .I think it's the headlight switch on mine. . .and I have heard that it is a good idea to upgrade to the HD switch anyway so that is my plan. . .I know why I don't have a seatbelt warning light and that's because it's unplugged at the seatbelt and the connection has been buried under carpet by the previous owner. . .
There is also one other thread besides yours and mine on dash lights that is active right now. . .so look for it on the first page or two of this forum

Hey Mechanic Again. . .check out my thread:

I got my lights to work by cleaning the printed circuit contacts with electrical contact cleaner and fine steel wool. . .I also cleaned the bulb holders and gauge nuts on the back of the dash panel with electrical contact cleaner and a wire brush. . .and I cleaned the turn signal switch while I was at it and I got rid of the annoying tendency of the right turn signal indicator to stay lit once the turn signal was canceled!!!
Your headlight/wiper bulb should illuminate when you turn on the headlights. . .
I also posted my results of testing the dash plug so you can see if yours match mine. . .I'm definitely gonna remove the blue lens covers and upgrade to LED's though. . .the lights are not very bright that is for sure!!!
