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 .

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

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.

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.

    • You could try a used 1, they used that engine in the Astro vans, Plenty of them in the boneyard. Look for a wrecked or rotted 1 so the chance that it was scrapped for that reason and not a mechanical issue will be greater
    • Google converting 98 4.3 spider injection to carburetor if all else fails. 
    • My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.  
    • The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.
