Hello, my first thought, is a problem with the wiring harness in the steering column. I don't have wiring info for your horn, but, the horn button or switch is usually just a ground. There should be a horn relay, don't have the location.
I do have a power distribution wiring diagram, it just shows voltage to the horn relay, doesn't show how the horn itself is wired. For the relay location, it just says junction box, I don't think that will help. You might just unplug the horns, not the relay, until you can find the problem. I don't know what else to tell you?
