Headlight activated by turn signal and turn signal activated by headlight

[Tristin Lorenzo]

So for some reason my turn signal (driver side) flashes the headlight instead of the turn signal. And when I turn the headlights on the turn signal instead illuminates (again driver side). Before this had happened I turned my high beams on and it turned my turn signal on indefinitely as long as my high beams were on I parked the car and in the morning the headlights and turn signals switched. Any suggestions on where to look first?

Read the instructions for popping the headlights out, and after you do that then check the wiring loom for the headlight.  At the age of our cars, the wiring insulation is very brittle and breaks off easily.  It may be that the wires have shorted.  The only solution is to carefully wrap the wires with electrical tape.  There is no replacement wiring loom for the headlights, and new replacement headlights are mega expensive.

Perhaps a bad ground and the current is passing through the other bulb on the way to a ground?

 

I had an MG that did this with taillights and a turn signal.

Bad earth, get this on the 986 some times after a hard bump, pull the headlight & reseat it, fixes it every time for me
