Well can't say I know exactly where to look next. Perhaps the combo switch, as suggested above by Southern Comfort. What happens when you start your wipers? Hopefully not the horn. I've had my own electrical gremlins recently, and I can sympathize. Not always easy to track down the source of the problem. Were it me, I'd start at the 'button' and methodically move from there through the wiring to the horns themselves.

The horns are under the front bumper, easy to access. The wires just hang there and I can imagine that they are fairly easy to damage. There's also a ground there. Don't know that you will find a problem there, but might be worth investigating.

As a way of isolating the problem slightly, you could disconnect one horn, and then the other, to see if it relates only to one or to both. It might help you to narrow down where in the wiring to look (or maybe not help at all, at least it's easy to try). Anyways just a thought.

Even more reason to try isolating the problem area. Are all horns on the same fuse? It sounds like maybe you have some aftermarket horns. If you installed them, then you have a good head start tracing the wiring. If not then tracing the aftermarket wiring to find a bad splice, etc. would be a good place to continue your search.

I agree with Beige240d. This changes the possibilities somewhat. Personally I'd disconnect all the aftermarket horns and get the wiring back to stock. If that cures the problem you can start over with the extra horns if you really need them.

Well to be honest the problem started waaaaay before the aftermarket horns
