Check the Headlight Switch. If your headlights come on automatically check the headlight sensor and its associated relay.

had the same problem on my 92....check under the hood on the drivers side,towards the front,there is a "junction box" with all of the lighting wires connecting from the switches to the lights.My wires were all corroded inside,so I cleaned the ends and bought a new box from the local electronic supply store.The problem has not come back.

Testimonial: "I will know tomorrow if that's the problem. Just getting home now with the high beams on all the way. Thanks in advance."
Have the same problem with my 05. Do you have fog lights as those will not turn on either. I thought it was the switch on the stalk but that worked the same when I changed it out. I did notice a bit of a melted spot. Relays and fuses good. I'm guessing a bad ground but WHERE

If you ran a separate wire to the lights, it's not a ground problem. looks like you may have a bad switch.
or bad wire. you can use an ohm meter to check the wire from the switch to the light. a test light is
easier. test for voltage at both ends of the fuse, at the switch and the wire before the light. check the
connection at the light, sometimes the connections get corroded and voltage will not pass thru. good luck!
