But an inoperative car horn can also be caused by a bad horn switch in your steering wheel, a broken “clock spring” under the steering wheel, a bum horn relay, a broken wire, or a corroded ground. Here’s how to check the most likely suspects: Start by checking the fuse. Refer to the owner’s manual for its location.
Typically, the fuse box is located to the left of the steering wheel at the base of the dashboard or immediately underneath. In some cars it’s located in a compartment underneath the hood. Look in your manual to locate which fuse powers the car horn.
How do you diagnose a horn problem?
Connect one clamp to the terminal on the horn and quickly touch the other end to the positive battery terminal. If the fuse blows, you’ve got a bum horn. If the horn makes a clicking sound, the problem could be a poor ground connection. Clean the horn’s ground connection and try powering the horn again.

Can you drive without a working horn? Your horn is a safety feature, so it stands to reason that it should be in good working condition. Most problems with your horn would only result in a minor fault on your MOT, but if your horn is not working at all, your vehicle will be deemed unroadworthy.
If you remove the horn fuse and don’t replace it, that circuit will be “broken,” so the horn won’t work. If you removed the fuse for the radio, the radio wouldn’t work. If you removed a fuse or breaker for the ignition or fuel injection systems, the car wouldn’t start (assuming it’s a gasoline-powered vehicle).
