It's up under the dash on the drivers side. Remove the panel under the steering column (3 screws) and reach up toward the drivers side mirror. There are 4 relays located there. The horn relay is the square grey box, about 2 inches square. Press the horn on the steering wheel and you should feel and hear the relay clicking. GOOD LUCK !!!
