Unless it changed from the '90s models, the horns are to the right of the radiator, very well hidden. Typically one will short and the fuse will blow. If your fuse is okay, chances are the horns are too. A much more common cause of a dead horn is a defective clock spring. That's a wound-up ribbon cable in a plastic housing under the steering wheel. An additional clue is you will not hear the horn relay click when you press the horn button. As the ribbon cable continues to break, eventually the cruise control will stop working and the air bag light will turn on.
