Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Replace the Horn Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse for the horn (check the owner's manual for the exact location).
Inspect the fuse for signs of damage; replace it with a fuse of the same amperage if blown.

3. Test and Replace the Horn Relay

Find the horn relay in the fuse box or under the hood.
Remove the relay and test it with a multimeter for continuity.
If faulty, replace it with a new relay of the same specification.

4. Check and Replace the Horn

Locate the horn assembly, usually mounted in the front of the vehicle.
Disconnect the wiring harness from the horn.
Use a multimeter to test the horn by applying direct battery voltage.
If the horn does not sound, remove it from its mounting and replace it with a new horn.

5. Inspect the Wiring and Horn Switch

Visually inspect the wiring harness for any frays or breaks.
If damaged, repair or replace the wiring as necessary.
Test the horn button in the steering wheel for continuity; if defective, consider replacing the steering wheel assembly or horn switch.
