To remove the horns, locate them behind the front bumper on the right-hand side. In some models, access can be gained from above; if not, firmly apply the handbrake, jack up the front of the vehicle, and support it on axle stands. Remove the retaining screws and fasteners, then take off the undercover to access the horns. Disconnect the wiring connector(s), slacken and remove the mounting nuts, and take the horn(s) out of the vehicle. For refitting, follow the reverse process of removal.
