Dash lights don't work - The 1947 - Present Chevrolet & GMC Truck Message Board Network

None of my dash lights work in the '74 except the turn signals, bright indicator and the brake indicator. All of the bulbs have been changed.
Besides the obvious fuses what could be causing this? Possibly a ground issue? Where are they grounded to? What things should I be looking for? Any help would be appreciated.

I know it's a dumb question and I don't know if the lights you have that are working, work with the others in this way or not, but I KNOW it's happened to me several times.

Are they dimmed too much? I can't tell you how many times mines been dimmed down by accident and I think all the lights stopped working.

I did check to see if the light were dimmed too much but that was not the problem. I was thinking of replacing the headlight switch and see if that works.

Check the switch and the dimmer switch also.

Sometimes the printed circuit behind the cluster goes bad. Mine was all sorts of screwed up, if I turned my lights on the gas gauge and voltmeter stopped working, but they worked fine with the lights off. Half of the light bulb sockets were dead too.

they ground to the side of the cab right behind the dash. as for anything else check the plug it might be off a bit. also check to if you have any dead ends in the circit board

twist the lights knob counter clockwise...if that doesnt work...then its further out than I can manage

Check your tail lights , I think they are out when your dash lights go out . My 77 in highschool used to lose the dash lights and it was an indication that the tail lights were out . Mine was a pinched wire between the bed and frame . Frank

The tail lights do work as do all other exterior lights. I got a different cluster to try. We'll see if it works.

Well the different cluster didn't do anything.
