My 92 has a problem with the highs coming on when I turn on the left turn signal. Try pulling back on the turn signal post just a little bit with the headlights on and see if that makes high go off. What do I need to do?
I had that happen to an old van of mine. It ended up being a loose ground. Check the ground that bolts to the frame right behind the headlights. It's 4 wires crimped together (I think). Bad grounds can cause really wierd stuff to happen
Okay, I finally made the time to take it apart. the high lights flicker cause the parts are just worn. Cheap plastic parts are just made to wear, cant complain, lasted 14+ years. I will just have to dish out the $$$ and pick up a new combo switch assy. At least I learned how the lights work now and can take it apart blindfolded now.
