headlight switch replacement

[charles leroy Jensen]

Hello my name is Charles Jensen I have a 1994 Ford Explorer when I pull out the knob for my headlights just my parking lights show up recently. I've been reading that it is typically the headlight switch especially if all other lights are working and my question is how do I replace headlight switch.

I would check the switch with a test light to make sure the switch is faulty before replacing it
