07 Denali... No low beam headlights

[dougywarren]

Just got to my parents for Thanksgiving, 7 hour drive. Get ready to head out for the evening and no headlights. They won't turn on when I unlock or lock, or when I manually turn them on. Brights work so the bulbs work, nothing else seems to be a problem.

Anyone had this issue? relay? either way, I'm driving my mom's VW and I already miss my Denali and I'm embarrassed. first time I was going to show it to my home town friends.

Ugh.....

Hopefully it's an easy fix.

Check your bulbs? They are the 2 in one bulbs correct? Try replacing one and see if it works

Check fuses and bulbs like SUMO said. check your harness connections too.

Relay and fuses are good. Being Thanksgiving I didn't go out and swap bulbs, but my guess is they're both fine. High beams work and the chances of both low beams going out at the exact same time is strange.

But not impossible. Working at a dealership, seen this happen more than a few times. Also do you have hid? Have you checked your sockets? May have melted harness from heat from aftermarket bulbs or hids

The 2007-2014 Yukon's use a H13 dual filament headlight bulb. You say you have "hi beams" so this would indicate to me that your fuse and relays are good.

Turns out both bulbs were burnt out. Forgot to respond to this. But how weird is that. Never in my life have I ever experience that personally, or with anyone I knew.
