I have a 1979 Z28 Camaro - the dash lights are out-left brake light out-left trun signal out. Everything else works fine. I tried changing the 3amp fuse but that did not help. Can anyone help? :confused:

Looks like you have quite a problem there! All of those circuits have separate fuses. I would first check the turn signal/brake light bulb, they both use the same filament in the bulb. Check the ground at the brake light too.

For the dash lights, do they work if you you rotate the light switch full counter clockwise? If they do, the rheostat in the switch has an open circuit. Even if they don't, you need to see if there is power coming out of the switch on the dark green wire. That goes directly to the instrument lights fuse. Tell us what you come up with.
