Kind like plplplpl is saying, I wonder if the horn itself does not work. If so, maybe an alarm is going off all the time but you can’t hear the horn.
Does it have an aftermarket alam.
I would probably do a parasitic Voltage draw test to help narrow down the problem. Disconnect the horn and see if the voltage draw goes away. But, I would also thing that if the horn were drawing power all the time it would be hot to the touch.
