2007 Frontier low beams will not work

[steve sparks]

Here's what I have done. I checked wiring at bulb sockets low beam side no power high beam has power. Checked fuse block under hood both low beam fuses are good but no power across fuse block, downed relay for low beam swooped relay no power. Bought new headlight switch no low beam lights. Am I missing another fuse in side the truck our under the hood possibly?

Hey Steve, welcome to NICO Club! I'd just check all the fuses in both boxes (under the hood and under the dash). Then I'd swap some relays around from known, working systems. Be sure to use a voltmeter to check the fuses for continuity, don't just rely on the old eyeball method. You can find all the details as well as wiring diagrams in the FSM if it comes down to it. Here's a link to help you find that:

When you say "no power across fuse block" be sure you're checking the hot pin to ground, not to the other pin that feeds the headlights. I have made that mistake before...
