Reason headlights not working
I need some suggestions. I have a 85' F350 w460. My headlights stopped working on me a few days ago. All the marker, taillights, and turn signals work. I checked my fuses, and I replaced the dimmer switch (high/low beam). It didn't help. Do I need to try replacing my headlight switch? Can it be as simple as both headlight bulbs going out at the same time?

Not likely to be both headlights going out at the same time. Much more likely to be the wire leading to the switch, or the switch itself. The wire is a known failure point, so look at the wires to/from the switch for melting, burning, etc.

An easy thing to do is get a testlight or voltmeter and then pull the new dimmer switch back off the floor. Pull the connector out just a little bit so you can probe the terminals, and then turn the headlight switch on. If you have voltage down at the dimmer switch, you know the headlight switch is working. If you don't, you know the problem is at the headlight switch.

Ok I found the problem. It's a few melted wires going into my dimmer switch.
My question now is, can I just cut & splice where the wires are melted at? Or do I have to completely re-run the wires from where ever they came from?

You can cut and splice, assuming there isn't damage elsewhere. BUT, you have to fix whatever caused the problem first, or it'll come right back. If the problem was a bad dimmer switch or connections thereunto, replacing the switch and connectors, along with replacing the wire that is melted, should do it.
