Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace the Fuse

Locate the fuse box under the dashboard or engine compartment.
Remove the horn fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Inspect and Replace the Horn Relay

Locate the horn relay in the fuse box.
Remove the relay and test it using a multimeter or replace it with a known good relay.
Reinstall the relay securely.

4. Test the Horn

Disconnect the horn from its mounting location.
Use jumper wires to connect the horn directly to the vehicle battery to check if it sounds.
If it works, proceed to the next step; if not, replace the horn.

5. Check the Horn Button and Wiring
