On my 1996 Ford Explorer when I turn the knob for my headlights (3 positions, 1 for off, 2 for parking lights, 3 for headlights) to position 2 it turns on my headlights, when I turn to position 3 it also activates the headlights.

Why does position 2 engage the head lights instead of the parking lights?

  • I'd suggest the switch is probably worn out, but that would be a SWAG on my part. Apr 23, 2016 at 22:31
  • SWAG? -- How would I check the switch? Apr 23, 2016 at 22:32
  • Does the car have Auto Lamps? Is there a sensor on the rear view mirror? It could be a switch or the car is designed to do this.

    Those Ford rotary switches tend to break and do just that. Thankfully its really cheap to replace and you can do it yourself. This is the switch: justanswer.com/uploads/FordKnowledge/… Here is how to do it: youtube.com/watch?v=ROLzKlwSb68 The part:ebay.com/itm/…

    To test the switch, it get's power from the tan/white wire, in park lamp it sends power to the white/light blue wire, and in head lamp position it sends power to white/light blue & red/yellow wires.

I suspect the contacts in the light switch are shorted.

In a correctly working switch,

  • In the off position you wouldn't have power on white/light blue or red/yellow.
  • In the park lamp position it would only have power on the white/light blue wire.
  • In the Head lamp position it sends power to the red/and white/light blue wire.

If none of these are true than the switch is bad.

You could also disconnect the switch connector and jump power from tan/white to white/light blue and if the headlights come on than the problem isn't in the switch but in the wiring.
