Horns are a simple circuit to check. Check for power and ground at the horn while an assistant holds the button. If you have both, the horn itself is bad. Newer cars are usually ground side switched. If there is no power, check the fuse. If there is no ground, it could be a few things: the switch itself, the relay, the clock spring in the steering column, or a wiring issue. I recommend having a certified technician, such as one from YourMechanic, come out to your car's location to run a diagnostic inspection of your inoperative horn, and suggest the best path to repair.
