A week ago my 1993 Mazda Mystere MX6 was working perfectly fine with th eheater on and the radio. It was night and all of the lights on the dash were bright.I turned on my left turning signal and all of the lights dimmed and the radio and heater quit. The headlights and everything else were fine. Then, the dash lights flickered and came back on real slowly. Th ebattery and fuel lights came on for about 10 seconds. I asked a mechanic and he said it may be a ground short circuiting, but to ask around. Help! Can anyone tell me what this is? No one seems to be able to fix it.
