Is Your Car Horn Not Working?

Having a working horn is necessary to pass a state inspection and also improves road safety for you and others, as it allows you to communicate warnings to other drivers and pedestrians. The horn can also serve as a security feature on certain vehicles, helping to deter potential thieves or vandals when activated by the alarm system. Most car horns use a diaphragm moved by an electromagnet, which moves air through the housing to amplify sound. Your vehicle may also have more than one horn, and often these are set to a high and low pitch to ensure that other drivers can hear you. Over time, your horn can stop working due to a blown fuse, a faulty circuit, or a broken relay connection, or the horn's diaphragm or internal electrical connections may suffer damage and prevent it from working. If your horn won't honk, or if it is noticeably quiet or sounds weak, O'Reilly Auto Parts carries horn replacements for most vehicles. We also have custom aftermarket replacement horn options for higher volume or custom sound applications. Check out our selection and let our part professionals help you find the right car horn to fit your vehicle.
