in the TIPM box. all fuses in 1 spot now. (and relays)
some have no fuse. and use electronics driver, (fuel pump is one)
i look in the box. the word horn does not exist. like my JK 08 has.
that means its fully electronic, as they keep doing (a good thing)
no fuse , no relay
the TIPM has a horn drivers.
the events (did you scan it first ) back in 2014?

BCM brain sees you do that.
BCM sends, digital command (networked) to TIPM the brain in the TIPM
turns on its horn driver transistor sending 12vdc to the horn
got 12v to horn honking key on? if yes, the horn is bad, or its base ground is rusty, as all do in the salt belt (wiki that)
