Has anyone been able to replace the stock horn without removing the entire front bumper? The 2015 horn is located in a place I can't reach... If I could remove this plastic lip I could reach down, but there are these plastic rivets unlike the others I can't pry loose.

 

I removed the horn yesterday after I installed HIDs into my fogs. It's simple, use a plastic trim tool remover to remove the black fog light housing from the front passenger side. Once they are removed, reach in through the hole and you will see the horn mounted with a 13mm nut, loosen the nut, unplug and remove the horn. Hardest part (not that hard) was removing the fog light housing. I actually had to use 2 trim tool removers as the passenger side was pretty stubborn

 

Took off that passenger side cover, but there was a wall blocking access to the horn. Perhaps it's because I have the LX model? Anyways, learning the tab layout from the passenger cover made me more confident with removing the front grille thing. Took that off with a cooking spatula and replaced the horn. Thanks.

 

What type of horn did you use??

 

HONDA OEM-Horn 38100STKA02
It's what people used for the previous generation fits... I think mine may be defective, however, because it sounds like a little horn and a big horn in melody. That or there is another horn I don't know about.

 

There are TWO horns on my LX. one behind the right side front bumper and the other in the middle portion under the a/c condenser coils. If you wanna see pics - go the the "What mods......" thread. I replaced both with Hella trumpet horns. Now I get a honk instead of a high toned beep.
