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.
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.
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.
