I have a 1984 mercury fox with alot of electrical gremlins but the worst of all is the headlights. When i pull the headlight knob the interior lights all come on fine but no exterior lights come on. When i turn on high beams the low beams come on. Rear running lights do not come on when i do this. Highbeam indicator light only comes on when left turn signal is activated. This car is a field find that was full of mice and when i got it all lights worked fine but one day this started happening. Please help already got warning from police and dont want a citation.
