On my brother's new camaro (89 RS), when you turn on the lights, the turn signals and high beam indicator lights come on and stay on. As you adjust the dimmer **** it changes the brightness of the turn lamps and high beam light, and also makes the buzzer cut in and out. When I pulled the fuse for the instrument lamps (that's what I'm guessing it was; 5 amp fuse labeled inst lps) then it didn't do that. Somebody'd done something w/ the electrical system (a few extra wires and such. See the title of my post as to my guess as to who's responsible ) All the wires seem to be intact, no frays or splits, etc. Any ideas? Thanks, Joe

 

There is a ground problem within the system. My '83 Cutlass did that same thing when the ground for the rear harness rusted off. Check all ground points for loose or broken connections.
