Locate the fuse box under the dashboard or engine compartment.
Remove the horn fuse and inspect it for continuity; replace if burnt.
Reconnect the battery and test the horn.

3. Test and Replace the Horn Relay

Identify the horn relay in the fuse box.
Remove the relay and test it by swapping it with a similar relay.
If the horn works with the swapped relay, replace the faulty relay.

4. Inspect and Test the Horn

Locate the horn assembly, usually found at the front of the vehicle.
Disconnect the horn connector and use a multimeter to check for voltage when the horn button is pressed.
If voltage is present but the horn does not sound, replace the horn assembly.
