If you are saying the horn does not work when pressing the switch on the steering wheel? The best suspect is a broken clock spring. That is a wound-up ribbon cable in a plastic housing under the steering wheel. As it continues to break, other systems in the steering wheel will also stop working. Most commonly that is cruise control switches, and the red airbag light will turn on.
