Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the horn fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; replace it if blown with a new fuse of the same amperage.

3. Test and Replace the Horn Relay

Locate the horn relay in the fuse box.
Remove the relay and test it with a multimeter for continuity.
If faulty, replace it with a new relay.

4. Check and Replace the Horn

Locate the horn, usually mounted in the front of the vehicle near the radiator.
Disconnect the wiring harness from the horn.
Use a multimeter to test the horn directly by connecting it to a power source.
If the horn does not sound, replace it with a new horn.
Reconnect the wiring harness.

5. Inspect and Repair Wiring

Visually inspect the wiring leading to the horn for any signs of wear or damage.
Repair any damaged sections using electrical tape or by replacing the wiring.
Ensure all connections are secure and free of corrosion.

6. Test the Horn Switch

If the horn still does not work, remove the steering wheel cover to access the horn switch.
Inspect the switch for any visible damage or disconnection.
Test the switch with a multimeter; replace if necessary.
