1991 Escort GT with weird electrical problem
I'he had a strange electrical problem lately:
when the headlights AND the rear defrost are on, the engine won't
shut off. I turn the key to the off position, I get it out of the
ignition switch and the engine, the headlights and the defrost are
still on. At that point, if I turn either the headlights, OR the
defrost off, everything shuts off. It is only the combination
headlights-defrost that does that. If I turn the headlights,defrost
and heater-blower on, and I turn the key to the off position,
the heater-blower will shut off but not engine-headlights-defrost.
Headlights-heater-blower, defrost-heater-blower everything shuts
off fine. I replaced the ignition switch & lock cylinder. What to check now?
