Solution

1. Preparation

Required Tools: Socket set, multimeter, screwdrivers, safety gloves.
Disconnect the battery to prevent any electrical shock or short circuit.

2. Replace the Horn Fuse

Locate the fuse box and find the horn fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.
Reconnect the battery.

3. Replace the Horn Relay (if necessary)

Identify the horn relay in the fuse box.
Remove the relay from its socket.
Install a new relay in the same position.

4. Inspect and Replace the Horn

If the horn is faulty, remove it by unscrewing it from its mounting location.
Disconnect the wiring harness from the horn.
Install the new horn by connecting the wiring harness and securing it in place.
