Gauge lights out, no fuses blown
 

My gauge lights decided to go out one night and I can't find any reason why. The signal and the blue light which indicates that the headlights are on works on my dashboard but the lights behind the gauges don't (speedometer/rpms/gas/temp) and my highbeams wont work. It all happened at once, not one by one. What could be the problem?

I would've said a fuse, but you say none blew. I assume you checked the interior fuse box as well. I wonder if a wire got loose?

check your dimmer switch, that could be the culprit

pull the dimmer switch and jump it light will work again, just had to do it with mine
