Weird electrical issue

[rycar550]

So after picking my car up from the valet (first problem) I noticed the following:
--No instrument lights in dash are working
--passenger side tail light not working but bulb looked good
--license plate lights not working

Headlamps work, instruments function, all brake lights work, turn signal and indicator work.

Fuses 21 and 10 are good. Any suggestions?

Don't know where to begin.

I'm sure this is obvious, but did you make sure the instrument lights were turned up?

Yes, I checked. Wish it was that easy...

The only thing those failures have in common that I can think of is the headlight switch, so I would begin there. The rear lights are hopefully just bad connections or oddly timed bulb failures.

Same issue

I have the exact same issue that I have been trying to figure out for a few months. So far I have replaced the passenger side rear marker light since it was an old POS I got from the junkyard and I have tried replacing the rear taillight housing which I bought off of here with the same result. It works for a little while when I replace the fuse but it blows within a few minutes, usually after going over a small bump. I have looked all over the wiring harness and I can't find a problem anywhere.

I will keep you posted if I figure it out and I will be watching this thread if you find your problem.
