Question Headlights quit

Ok guys. I noticed the other day that my headlights won't come on. Every other light works. So far I replaced the dimmer switch, headlight switch in dash, new bulbs. Still no headlights. Any suggestions? Are there any fuses, or relays?

Thanks,
Pconant

There is no headlight relay but the headlight circuit is fused both behind the glove box door & inside the Power Distribution Center on top of the passenger-side fender well inside the engine compartment.

Should be a diogram on the underside of the lid on the one on the fender under the hood, but for the one behind the glove box Google is your best bet...

The fuse location for the Headlights is under the hood. 30A fuse location #10. If the fuse is good, you will need to get a voltmeter and start checking voltage at various points along the headlight wiring.(start at that fuse loc#10, headlight connectors, headlight switch. Also check the wiring at those locations for corrosion.

My headlights decided to quit on me at the most opportune moment, while I was in the middle of night wheeling . i replaced the headlight switch in the cab but that did not resolve the issue. I returned the new switch and re-installed the original switch.

Next I replaced the turn signal switch and voila, my headlights were working again . I believe the turn signal switch cost me approximately $34 at autozone.

Have you physically checked each fuse by now with a meter to verify its condition? Sometimes it is easy to confuse which fuse does what so at this point I'd leave nothing to chance.

It's a multifunction switch, so yes - it is possible that the turn signals would work fine, mine did when my headlights went out. My hazards (part of the turn signal switch) worked as well.

For me, there was nothing to indicate that the outage of my headlights correlated with my turn signal, everything worked on the turn signal. But the turn signal does impact the headlights i.e. high/low beam function. Again, when I replaced my turn signal switch - my headlights worked!

Just something to consider...

Ok, So far I've changed the switches, bulbs, a couple of fuses, plugs for the headlights(old ones were corroded. I checked volts at the plugs and I'm only getting .03 Volts. They should be 12 correct? What could cause the low voltage? Maybe one of the switches I bought is bad? Also, when I flip the dimmer switch to High beams, The indicator in dash doesn't come one. Anybody have suggestions? Please.
