The horn is located low on the passenger side, under the right headlight, where it is subject to road slush. After checking fuses, I'd check for corrosion at the terminal on the horn. If the airbag light is on and the horn doesn't work then you have a bad clock spring. That is best repaired by a certified technician.

swap the wires or run a lead over to the suspected bad horn and see if it blows. If the one horn blows and the other doesn't...then I would suspect the horn to be bad. If it blows using the lead from the good horn then you know the wiring is the suspect and need to track it down.
