Headlamps, hi and low beam, stopped working

[Morgan1058]

I'm having same issue with my 2013 GMC Sierra HD2500 now too. All lights work except low and HI beam headlights, when I pull turn signal toward me the HI beams do come on, so not a bulb issue. I'm thinking a headlight electronic solid state relay is bad that controls the headlights lights in the box under hood on driver's side .

My 2015 is doing the exact same thing at 64000 miles.  Any help?

So, was there a solution? My 2015 Silverado is doing the same thing. Which Relay needs to be replaced? #59 is labeled to do the Fuel Pump

Headlights both stopped working at the same time on my 2015 sierra1500 last night. fuse looks good. Anyone??

My head lights have been intermittent, but when I turn on the truck they usually come on then flash and go out. 
 

I have a 2015 GMC 3500 

 

does anyone know what causes this??? Is it the BCM?

Got in my truck

 

 

this afternoon and the headlights wont come on they are in the auto position. I tried moving the switch to the on position and no change. I'm thinking it's a bad relay but not sure. I tried locating the fuse for the headlights but can't seem to find that either I looked in both the driver side and passenger side door and under the hood and cannot find one looking for some help.

Same problem.  Anyone fix?

We just bought a 2015 High Country yesterday.  Got halfway home and the headlights would not come on.  I googled and landed in this forum. We stopped and bought new bulbs.  My husband put the driver's side bulb in and it did nothing.  We drove home with only DRL and fog lights which was quite scary out in the country.  Pulled the truck into the garage and the driver light started working.  Replaced the passenger bulb (which was much more of a pain) and now both headlights work.  High and low beams.

Seems to be a common issue. I have a 2500 GMC HD Denali and same thing...ugh

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.

My headlights flicker and go out. Shut off truck and restart a couple times and they start working for awhile.  Happens more when it’s cold. Did you find a solution?

2015 GMC Sierra 1500. Headlights flicker and quit, seems to happen more when it’s cold outside. I have to shut the truck off and restart it a couple times then the lights work again. For awhile. Sometimes seconds. I’ve checked grounds, wires even a $600 mechanic bill. Still does it randomly. 
something new, tires spun at an icy intersection yesterday and headlights quit

Hello, my truck had the wrong HL in it. Had 2016-19 HL. Had to change them back to 2015. This truck came down from Canada, I bought it used. I'm sure there is a story behind this, but I'll never know what it was. That work great now.
