If you are referring to the horn...there are a few in sometimes different locations. Should be one close to the driver side wiper motor under the hood. Believe this one is for the alarm.
As far as the horn button in the center of the steering wheel...horn/horns could be located in inner wheel well on one or both sides of bumper.
Another location is once hood is raised , directly in front of radiator.
Hope this helps you........
