Dash Lights Stopped Working

[Gray035]

Turned on the headlights the other day and all the instrument lights stopped working all at once. I saw them come on for a second and then...nothing. All the instrument cluster lights and the indicator bars under the wipers knob headlight knob etc. I thought it was possibly a ground issue but I haven't found any grounding problems yet. Any ideas about where I should start?

the fuse box?

Try rotating the headlight sw knob. If they still don't work look at the short fuse in the fusebox.

Check your headlight dimmer switch. Seriously. I spent a lot of time and money trying to fix mine and it turned out to be corroded connections/faulty dimmer switch. Others have found the exact same thing.

When I put a new fuse in none of the lights work. When I turn the dimmer all the way to where it clicks (to turn on the dome light, which I don't have) the fuse blows. Any ideas?

You have a short it there somewhere...Look behind the dash to make sure there are no naked wires rubbing or touching.....has it got wet anywhere in there lately?

A short to ground in the black-blue wire. That's map light (near cluster) or dome light (through windshield frame).
