I need to remove the column anyway, but I am having a weird gauge, headlight/interior light issue. The problem is that if I turn the headlights on or brights everything is fine, but if I turn the headlight **** (with the headlights on) to turn on the interior lights, my oil pressure gauge and fuel pressure gauge drop to zero. Headlight switch is new, I even tried a gauge cluster out of a 1990 camaro (interesting side bit of knowledge, the 1990 camaro oil pressure gauge reads from 0-80 and the gauge cluster out of my 1991 camaro reads 0-60), but same issue occurs with both clusters. I am assuming it's a ground issue somewhere, but I wanted a little more input, so I know what to narrow in on when I take the steering column out to fix the tilt steering pins that are shot.

 

I agree, likely a ground issue. I would take some of the covers off and check the grounds. I believe there is one near where the fuse box (going to one of the supports and i had one to the metal behind the dash. I got to it w the dash pad off. You always can add grounds but its best to find the issue. Id specifically start w a schematic and find the ground for the dimmer and the gauges (its probably the same?)
