The horns are located behind the grille, in front of the air conditioning condenser, and the easiest way to access them is from underneath the vehicle after removing the lower engine splash shield. First, raise the vehicle and secure it on jack stands. Next, remove the lower engine splash shield. Disconnect the electrical connector from the horn that needs replacement, then remove the horn mounting bracket bolt and take out the horn, separating the bracket from it. Installation is done by reversing the removal steps.
