A Horn Relay is an electrically control switch amperage current, controlled by horn ring to switch at relay. Relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits, repeating the signal coming in from one circuit and re-transmitting it to another. Relays were used extensively in telephone exchanges and early computers to perform logical operations.

A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor. Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called "protective relays".

The horn is behind the front bumper or grille somewhere. the relay is probably behind the dash inside the vehicle. when you push the horn do you hear a ticking noise? if you do, follow the ticking noise to find the relay.(it makes the noise)if it makes the noise, it probably works and you should check the wire connection to the horn unit. it looks like a nautilus, sort of a coil resulting in one open end, pointing down.it is about the size of your hand. if it does not make a noise it would probably be your horn fuse or your switch.
