Headlamps, hi and low beam, stopped working

[natesimpson74]

2014 GMC Sierra 1500, Last night I got into my truck and neither my high beams or low beams would turn on in my truck. The fog lights, turn signal/marker lights, and tail lights all work. I tried auto and on on the switch. I tested for power at the headlight fuse and did not have any with the headlights turned on. The light on the dash turns on indicating that the headlights are turned on.

 

Any ideas where to look? I cant seem to find anything that shows where a headlight relay is. What links both high and low beams other than the BCM? Of course my truck is 4000 miles out of warranty.

 

Any help is appreciated! Thank you.

F.Y.I. The high and low is only 1 bulb per side. The GMCs have a shutter that covers the bulb slightly in low mode and when in high mode the shutter moves up out of the way and exposes the whole bulb to shine through the projector lenses.

Headlight concern?? That's more of an emergency IMO.

Check the ground wire going to the low beam plug.

fuse 59 it is a 3 wire fuse

[Chev-mekanik]

Replace bulbs.

Hey, did you have any luck with this? I'm having the same issue.

[Christian B]

Yes, both headlights went out simultaneously.

[Darrell Chaisson]

Did you have any luck resolving this issue?  Both of my headlights quit working this morning,  bulbs are both good, fuse is good, etc

I have a 2015 same issue with headlights. Been to 2 shops no help. When mine go out they flicker then out. All other lights work.

[Brockgibby]

I have had the exact same problem as Nate. Did this get resolved?
