Hmmmnnn. I have the EXACT same problem with my 95-3.1 with stock delco radio/cassette. I have yet to find the cause although I suspect some component in the chime /radio circuit. Seems the radio light is very, very bright when switch and headlights are off, an really dims when I turn them on. I too unplugged the fuse and now do not have a radio that keeps its program or the chime to tell me if lights are left on , etc. I finally just decided to leave the fuse out, went and bought me an XM Radio Roady II (39.95 + $12.95/month)and now I don't worry about the short so much. ( left the fuse out and I'm still trying to locate the source of the short..I'll definitly let you know if I find it.. In meantime, buy you an XM (better anyway)
