The horns are well situated under the plastic hoods that are just in front of the fascia and above the upper radiator support. It is started by the removal of the plastic covers extending from the front bumper cover up to the upper radiator support. Secondly, unplug the electrical connector from the horn to be replaced; it is located beneath two small plastic trim plates. Subsequently, turn the horn mounting bracket bolt to be freed, then the horn and bracket are to be removed, and ultimately the nut to demerge the horn from the bracket. Move on to the next step and take out the horns and mounting bracket as a single unit, it is advisable that the electrical connectors of the horns are disconnected. To replace either horn, remove the horn retaining nut, then the horn then remove that horn from the mounting bracket. Last comes the steps of installation which, as previously, are performed in the opposite order to the removal ones.
