Highlights Flickering

[Treachery]

Driving at night with my headlights and fog lamps turned on, the headlights, fog lights and interior dash would turn off for some reason. The lights will then turn on again.. then off..etc. 1993 Mustang GT.

Needless to say that this is quite dangerous. I've checked all the fuses they look fine. All plugs seem to check OK as well.

What could be causing this?

Bad ground. I would look around, start looking at the one by the battery.

Bad ground it could be, but it could be any loose connection. Also, when it starts to do this, play with the dimmer knob, it can cause this as well if the resistor carbon tracks.

SEE http://www.corral.net/tech/maintenance/foglights.html to fix the problem. The stock wiring isn't up to the job and is overheating. The headlight switch & turn/multifunction switch are affected by Ford's wiring problem. Sometimes it overheats so badly that the plastic shells of the wiring connectors start to melt.
