The horns are located behind the left end of the grille, where they are bolted to a frame upright at the left end and in front of the condenser. Begin by removing the grille, followed by the horn mounting bracket bolt. After that, take out the horns and mounting bracket as a single assembly, then disconnect the electrical connectors from both horns. To replace either horn, remove the retaining nut for the horn you wish to replace and then take that horn off the mounting bracket. Installation follows the reverse order of removal.
