Try to operate the horn and listen for a click from the horn relay probably located under the hood. If you don't hear a click I would check out the horn switch contacts in the steering wheel. If you hear a click I would check for power at the horn using a test light. If you have power at the horn connection when horn switch is activated it is probably the horn itself that is bad. If you have no power at the horn connection when the horn switch is activated replace the horn relay.
