How to Fix a Car Horn That Won’t Stop Honking

The fastest way to make a malfunctioning horn stop honking is to pull the horn fuse or the horn relay . Failing that, if you are unable to immediately locate the correct fuse or relay, pulling the main fuse or disconnecting the battery will also allow you to address the problem without damaging your hearing.

Imagine you’re driving down the road, minding your own business when suddenly, your car horn gets stuck and won’t stop honking. You’re stuck in traffic, and everyone around you is glaring at you because of the noise. What can you do?

Luckily, there are a few things you can try to fix a stuck horn. In this post, we’ll go over the steps you can take to get your horn back to normal.

First, try shaking the horn button and giving it a couple of taps to see if that loosens anything up. If that doesn’t work, pop the hood and find the fuse box. Look for the horn fuse and remove it. If the horn stops honking, then you know it was a fuse problem.

If the fuse isn’t the issue, disconnect the horn at the source by pushing down on the connector and sliding it off. Most vehicles have two horns, so you’ll need to do the same on the other side.

Another common problem is a bad relay. Find the relay for the horn and remove it. You can put the fuse back in and see if the horn is still honking with the new relay. If not, then the relay was the problem.

If you’re still having issues, then it could be a problem with the horn button, the comfort module, or the body control module. It’s also possible there’s a wiring issue or an aftermarket accessory causing the problem.

To fix the problem, you’ll need to do some troubleshooting. If you’ve had any experience with this issue before, leave a comment and let us know how you fixed it.

In summary, a stuck horn can be frustrating, but there are several things you can try to get it working again. By following these steps, you’ll be able to troubleshoot the issue and get back on the road without any honking.


Why is my car horn honking by itself?
If your car horn is taking on a life of its own it could be due to the following issues: A faulty relay. A short circuit. A faulty horn push button.
How do you disengage a car horn?
How do I disconnect my car horn? The easiest way to do this is to pull the horn fuse, usually located in the fuse panel under the steering wheel. Look for a cover on the underside of the dashboard, when you remove it, you should see a grid of small, colorful plastic rectangles with numbers printed on them.
How do I know if my horn relay is going out?
If the horn makes no sound or sounds different, or if you cannot hear a click from the relay when the horn is pressed, replace the horn relay.
