-
Check the Fuse: Locate your car’s fuse box (usually under the dashboard or in the engine compartment). Consult your owner’s manual to identify the horn fuse. Remove the fuse and inspect it visually. A blown fuse will have a broken filament. Replace it with a new fuse of the same amperage. If the new fuse blows immediately, there’s a short circuit somewhere in the system, requiring further investigation.

Test the Relay: The relay is a small switch that controls the power to the horn. Find the horn relay (again, your owner’s manual will help). Swap it with a known good relay (from a similar circuit in your car).
