Dash lights quit working two years ago and I cannot figure out where the problem lies. I bought a new dimmer/headlight switch and that didn't fix it. I bought a used instrument cluster and that didn't fix the problem. I am still driving the truck with no dash lights. If anyone knows where this problem lies, I'd love to know. The odometer is lit as normal and when you move the dimmer wheel they become dim or bright as you like, the dash lights will not work.
