The horn is located at the tower right corner of the vehicle, in the void ahead of the right front wheel well. Begin by raising the vehicle and supporting it securely on jackstands. For 2007 and earlier models, remove the lower splash shield. For 2008 and later models, take out the left front fender splash shield screws and pull down the splash shield. Next, disconnect the horn electrical connector, then remove the horn mounting bolt and take out the horn. Installation follows the reverse order of removal.
