I'm having a weird electrical problem on my 99 Mercury Mystique LS Sport, Zetec auto. I've tried searching but never found a problem like mine. When the I turn the key to the RUN position the lights turn on. The headlight switch is in the off position. Everything seems to work, can turn highbeams on and off, fog lights on and off, hazards and turn signals. Also without the key in the ignition and if you turn the headlight switch, it like having the key in the RUN position. I can turn the heater on, move the windows up and down. The radio will not turn on though. If I turn the ignition off while the headlight switch in on, the car will keep running until I turn the headlights off. Right now I've unplugged the headlight switch and the turn signal switch but the lights still turn on when you put it in the RUN position. I've pulled the DRL and headlight relays but had no effect other than the headlights not turning on while the instrument panel is still lit up. Any help is much appreciated.
