  1. I am having some problems with my dash lights; they don't work anymore. The tach and all gauges work, the interior lights work but no dash lights. Dose anyone know of anything that could cause this or know how to supply power back to them?
  2. Jiggle your dimmer switch. run it back and forth a bunch of times, tends to clean off the rheostat. I have to play with mine now and then when the dash lights go out. If you have a constant power source to it and the fuse is not blown the switch is at fault.
  3. Must be the switch, but I have been jiggling it around maybe just have to get a new one.
  4. Ok, I do not think that it is the switch. I had it out and there was no power to it. Does anyone know how to get power back to these lights, could I rig it up some how so that they come on with ignition power?
  5. I know this is obvious, but..... a blown fuse? The fuse for the dash lights is #4 (15a).
    It sounds like it may have shorted out somewhere, in which case you'd have to either hunt the short down, or run a new power source to the switch.
    I don't know, I'm just guessing.
    Good luck with it!
  6. Checked the fuses and all are good.
  7. I have a couple lights that are bad. How hard is it to change them?
  8. It is not hard to change the bulbs, all you have to do is take the gauge cluster out and all the bulbs are on the back side just twist remove and replace.
