'92 L6. I've seen this on here a few times, figured I'd post a success story. Dash lights and running lights both went out at the same time. Figured it was a dash wiring problem, cuz the guy I bought it from was a little too splice-happy. Checked the fuses, which were fine. I figured, "what the hell..." and bought a replacement switch (the one on the left side of the steering wheel that controls both dash and running lights). Plug and play in about 10 minutes and everything works fine.
