Horn Continuously Blowing 2014 -2019 Silverado/Sierra - How to Fix a Horn That Will Not Turn Off!!

Just to clarify, the horn relay went bad. The horn relay is integrated into the fuse box circuit board. For that reason we needed to replace the whole fuse box.

Man I wish I would’ve found this video sooner. I ended up unplugging one horn, such a huge pain in the ass to access them. This video is a lifesaver! Gonna replace my fuse box. Thank you!

Clutch vid and breakdown! Just experienced same issue with my 2014 Sierra. Thank you.

Just got back from lunch, parked my '15 Silverado in my office parking lot and had the same issue with the horn. Pulled the fuse and then went to google and came across this video. Thanks for posting!

Dodger fan in Texas? 😃 Great video. You've been a lot of help for me and my 2018 Silverado. Thank You!

Just picked up a new to me 2018 LT Z71 last month and the other day woke up the neighborhood with the horn blaring continuously. Pulled the fuse, and ran inside to research what it could have been caused by. Thanks for the video! New part is ordered.

Just had my '17 horn do the same thing at baseball practice. After reassuring the spectators I wasn't stealing the truck, I ripped the fuse out. This issue has plagued me since I bought the truck in '17. Thanks for the vid sir

I had an issue with the high beams on my 2017 Sierra indicating they were engaged and not actually getting brighter >>> Forums suggest, you guessed it, it's a bad, non-servicable relay on the same fuse box/board! Truck wouldn't start without a jump, and then proceeded to die shortly after. Alternator? Per my mechanic, the repair guides suggest it's the fuse box/board.... Local Stealership has none and says they are on national backorder and has no idea when they will come in. I noticed my horn was no longer working when locking up with my FOB either. I'm hoping the trifecta is ALL this crappy board! 🤞🤞 Currently ordered with overnight shipping for the same cost the dealer wanted anyway. Can't risk driving the truck and not knowing whether it will start and die while driving or even start at all! Thanks for a great video! I'll come back to comment to update what issues the swap fixes for me.

So anyone else regret having a Chevy? It's amazing how the basic components of old vehicles last a decade or more and current vehicles are basically crap straight from the factory. I think I need to "accidentally" leave mine unlocked and find something reliable.

Thanks for showing this problem and how to fix it. Do you know what in particular went bad with the old fuse box?

Great video, did your truck also have the engine light on?

Great video! I’m having some trouble with my horn not beeping when I lock with the remote. But it does beep from the steering wheel. Any suggestions? It also once in a while gets stuck when I beep from the steering wheel but it stops once I give it another push. Thanks

So was this caused specifically by somthing or just normal wear and tear? Thank you very much for the video.

Hey man I just had this same issue but when I looked at my fuses there’s a wire running to fuse 39 which is misc ign. Would that affect anything if I swap the whole harness like you did?

my truck does this randomly only when i lock it with my key fob it will honk so loud until I have to unplug the fuse. Also not sure if this is related but the chime volume cabin (seatbelt,sensors,open door) is extremely loud I have it on the lower level but something is wrong the chime :( maybe this can fix it.

Would this be the same for a 2011 truck also? This just happened to me this morning.

do i have to replace the whole box? can’t just replacing the small fuse itself fix the issue ?

Horn stuck when I hit the horn at a driver backing onto the road. The fuse eventually blew. Replaced the fuse. Horn started the same thing after hitting the horn a couple of times. Wonder if there is a recall?

Hey man I currently have the same problem. What made you figure out it was that? Not like the clock spring or something else.

what made you decide to take out the fuse box
