What makes a car horn only honk with an alarm?
If amperage draw is greater than 20 amps without the horn switch depressed, a grounded circuit exists between the fuse and the horn relay. Proceed to Step 4.
Why does my car horn make a weak sound?
Bad connection, bad relay, bad fuse. It depends on whether your car horn is directly controlled by the horn switch of if there’s a relay involved. If no relay, the problem is most likely the horn switch itself. Sounds (heehee) like a bad ground.
Can a two horn car horn stop working?
In the latter case, it’s possible for just one horn in a two-horn pair to stop working. If that happens, you will notice that your horn doesn’t sound right anymore, since each horn in the pair produces a different note . The problem with this type of “fail-safe” is that you won’t know the system has failed until you need your horn.
Where does the power come from on a car horn?
This horn relay will be connected to the horn switch, battery positive, and the horn or horns. When the driver activates the horn, the relay provides power to the horn. This creates potential failure points in the horn switch, the horn relay, the actual horn components, and the wiring.

What to do when your car horn doesn’t chirp?
Withthe hood open, try holding the switch closed and locking the car with the remote. If the car chirps you need to mend the switch bracket up a bit. I need to do it periodically on her car. 45 people found this helpful.
What happens if you disconnect the horn switch?
If amperage does not drop with both horns disconnected and the horn switch depressed, proceed to Step 6. (6) Using a continuity tester, with the horns disconnected test continuity of the X2 cavity of the horn relay to ground. If continuity is detected, the circuit is grounded between the Junction Block and the horns.
