Horn Button

When you press the horn button, usually located behind your steering wheel pad, it sends a signal through the wiring harness to activate your horn. Because your horn system is electrical, blown fuses, broken connections, or short circuits can all result in your horn not working or working erratically. A working horn is a necessary safety feature for your vehicle, and may be necessary to pass state inspection depending on local laws, so if your car horn responds erratically when you press it, you may need a new horn button from O'Reilly Auto Parts. We stock OE-style horn button assemblies as well as universal and auxiliary horn buttons for use in equipment or for novelty horns to help you repair your horn button. Browse our selection and choose the right horn button for your vehicle.
