Things that could be wrong: Horn switch could be bad, horn fuse could be blown, horn wiring could be disconnected (or shorted), horn module could be bad. Find the wiring diagram for your car, get a multimeter out and check each of these things...start by checking the fuse, then by if your horn is seeing voltage when you hit the button, then by seeing if your switch has continuity when it's hit.
If there's no voltage at the horn, but the fuse is good and the button is good, it's the wiring. There could be corrosion on the terminals or a bad splice somewhere in the harness between power, the switch, the relay (sometimes), the fuse, and the horn.
