- Is your horn on your 2014-19 Silverado or Sierra continuously blowing, even with key out of the ignition? If so, in this video we explain how to fix this issue quickly and easily for good.
This issue is commonly caused by a bad relay located on the circuit board of 2014-19 GM trucks. The easiest way to solve this issue is to purchase a new Engine Wiring Harness Junction Block from your local Chevy or GMC dealer. The part number you will need to reference is GM 84303175.
This is an extremely easy fix for a very annoying issue. The unfortunate thing about this is that the Engine Wiring Harness Junction Block (GM Part Number: 84303175) costs approximately $260.00 at the dealership. So, this extremely easy fix is also an extremely expensive fix. However, if you follow the steps in this video, you can have your truck back to normal in no time at all.

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.
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.
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!
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
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.
Did the horn stop
Any one try to replace the relay? I'll bet its less than $5 for the relay.
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.
Can i drive the truck safely with alarm fuse removed until i fix it
I have a 2018 gmc Sierra, my horn would be weak when i locked my car sometimes. Has been weak since I’ve had it for 2 years. Randomly in a grocery store parking lot i pressed the lock button and the horn went off and stayed on no matter what i did. Had to disconnect battery. 2 cops even showed up and tried to help. Had to take the fuse out. Went home and took out the whole fuse box and cleaned it with electronics cleaner a too and wire brush. Put it back together and horn works better than before. Hope this helps someone.
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!
Clutch vid and breakdown! Just experienced same issue with my 2014 Sierra. Thank you.
Dodger fan in Texas? 😃 Great video. You've been a lot of help for me and my 2018 Silverado. Thank You!
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!
Great video, did your truck also have the engine light on?
Thanks for showing this problem and how to fix it. Do you know what in particular went bad with the old fuse box?
So was this caused specifically by somthing or just normal wear and tear? Thank you very much for the video.
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
How long can you use your truck before changing out the fuse box
do i have to replace the whole box? can’t just replacing the small fuse itself fix the issue ?
