The stereo in your vehicle may be equipped with an anti-theft system, so check the information at the front before detaching the battery cables. Note that checking the
Fuses is important before beginning electrical diagnosis. First, remove the front bumper. Next, unplug the electrical connector from the horn. To test the horn, connect battery voltage to the two terminals with a pair of jumper wires; if the horn doesn't sound, replace it, but if it does sound, the issue may be with the switch,
Relay, or wiring between the components. To replace the horn, unplug the electrical connector and remove the bracket bolt, then installation is the reverse of removal. Finally, install the front bumper.
