A Honking Big Jam (Stuck Horn)

April 23, 2023

At one time or another, most drivers honk their horn at someone who might be texting at a stoplight or not paying attention when they're driving.  But what happens when you tap on your horn and all of a sudden it won't quit? Everyone's looking at you like you're an angry jerk and all you want to do is turn it off!

It helps to know the basics of what's happening when you honk your horn.  There's a switch in the steering wheel, of course, and when you press on it, it sends power to a relay which then energizes the horn.  Bingo.  Sound.  When the horn sticks on, one of these parts or the wiring has developed a problem. 

With the ear-splitting noise inside your cabin, it may be hard to keep your cool, but do your best to stay calm.  Try pushing the horn several times; it may un-stick the switch if you're lucky.  If not, there are a couple of things you can try.

First, if you can, pull your vehicle off the road and into a spot where you're not disrupting traffic.  If you feel comfortable rummaging around in your vehicle's fuse box, you might be able to pull the fuse that manages the circuit for your horn system.  A hint: the fuse boxes sometimes have a label inside showing which fuse goes to which part of the vehicle. Find the fuse that goes to the horn and pull it out (sometimes there's a fuse-pulling tool inside the fuse box).

But many people don't feel like tackling that.  Yes, you can drive over to a service facility with the horn blaring (not the best idea).  Or call your service facility and see if they might be able to send someone over to where you are so they can shut off the horn.

At the shop, a technician can check wiring, switches, relays and other components to find out what's wrong.  This is something that should be left to a professional for a couple of reasons.  First, repairs around the steering wheel can involve airbags.  Second, some horn components may be part of a vehicle's alarm system. 

The bad news is that your horn may not give you any warning before it starts blaring uncontrollably.  But the good news is that a horn doesn't malfunction all that often, and now you have a plan if it does.
