Sounds like a short in the wiring to me. Any difference if you have the high or low beams on?

I got $1 that says the headlight switch is going bad...actually the part that dims the gauges/turns on the interior lights. Assuming you haven't done any wiring lately.

If the gauges actually go dead and stop working..then i dont think its switch related as much. seems more like a ground issue.
from off the top of my head, (i may be mistaken but im tired and ive seen similar situations) it seems the ignition power goes to the gauges and then doesnt have a good ground, possibly grounding back through the lighting circuit somewhere. when 12v are introduced into the lighting circuit, that connection being used as a ground for the gauges would get "taken over" in a way and therefore disable the gauge circuit. but like i said thats a quick guess and possibly my theory is flawed, i'd have to relearn 3rd gen dash wirign diagrams to figure it out for sure, if i have time and the energy i'll look at my schematics..
iroc-Z86, where are you located, seeing the car would help me more to track down the issue.

D'oh! I somehow read it as the gauge lights go out. D'oh.

sussex county, lower part. yeah i havent really had much 'will' to search the wires again because i had to learn it all because some ass put a remote start system in the car before i got it.....hmmm remote start+manual trans=??? interesting. well either way it didnt work and was screwing things up nicely. i figured since i cant drive my car yet i wasnt going to worry about it. wish i had the money for the digital dash... thanks for the input.

well i did some investigating the other day... it might be my headlight switch because if i turn the dimmer down to nothing the gauges work again, no lights but it works. the one turn signal arrow stays lit up now too. i think its either a loose connection in the back of the cluster and the headlight switch. anyone know the price of a new switch? any anyone have a cluster laying around because my speedo is clicking so its on its way out.
