Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Check and Replace the Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and locate the horn fuse using the diagram on the fuse box cover.
Pull the fuse using a fuse puller or pliers and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage (typically 15A).

3. Inspect and Replace the Horn

Reconnect the negative battery terminal.
Locate the horn, typically found near the front of the vehicle, behind the grille.
Disconnect the horn's wiring harness.
Using a socket set, remove the mounting bolts and take out the old horn.
Install the new horn by reversing the removal steps, ensuring it's securely mounted and reconnecting the wiring harness.

4. Test the Horn Relay

Identify the horn relay in the fuse box.
Remove the relay and inspect for any signs of damage.
Swap the horn relay with another relay of the same type within the fuse box to test functionality.
If the horn works with the swapped relay, replace the faulty relay.
