Horn is not working

[Nutro]

Cut those zip ties and un-bundle all of your wiring and see if the brown/white wire was looped back in and taped or something.

keep in mind the horn is a "normally open" circuit, the horn button serves as a ground.
the relay is energized at all times, touching the horn button closes the circuit (creates the ground)
so for testing purposes, press the horn button while checking with a meter along the circuit path
so horn button to bcm, bcm to fuse in fuse box, fuse to horn relay. relay to horn, horn to ground.

In my 2015, there was a thin harness tucked under the “carpet” under the console location. I pulled it out and found two cut ends of wires matching colors. They were the only wires in the harness. I don’t recall the color but with my research it matched what I was looking for. I stripped them and connected and the horn worked so I proceeded to permanently connected them.

Hope that helps
