It’s 3 am n I just got a call from police saying my horn is going off ugh now I’m watching this to try fix it 😂

Y'all are lifesavers! Encountered this problem just today. Took out the horn fuse. Now how do I fix it? 😂

Thank you, this video was extremely helpful!!!!! Our horn wouldn't stop and this video saved us!!!!

Thank you so much for this clear troubleshooting guide. My horn wouldn't stop beeping on my 2010 Honda Fit after I got in and turned on the ignition. And the doors locked me in, but fortunately the windows would still roll down, so I was able to get out. I'll troubleshoot as much as i can before taking it to the mechanic. They just fixed the AC a few weeks ago and I'm thinking they screwed something else up in the process, given the number of screwups they did all the way around.

Great video, well thought out. Thanx!

I knocked over a coffee sitting on the dash. The liquid poured over the steering column and the horn started to blare. I took out the fuse to stop the horn, then blew out the steering column and air bag component with compressed air. After a few days in warm temperatures, I blew it out again and replaced the fuse. All good.

Bought my son a car that had been previously in a minor front end collision, after about a month or so horn would go off in the night for no apparent reason. The hood was bent up slightly on the drivers side where the switch was, I disconnected the hood switch and no more random middle of the night horn disruption. Finally fixed the hood and reconnected the switch, all good now.

Thanks for helping! It was my horn relay and I found it just like you showed. New one on the way and due today.

I have an older Buick where the horn button is part of the airbag itself. Over time, the vinyl shrank. At first, the horn was sensitive, then it would go off by itself with temp change. I disconnected it and put an external switch since otherwise the airbag itself would have to be replaced.

You guys do it all 🎯

I really need help? If you know can you please tell me where is the really horn located on a 2006 Ford Expedition 2WD Eddie Bauer. The panel where the fuses are located doesn't tell which one is the relay horn. I appreciate every help. Thank you for sharing this video.

Great video, thanks! My '97 Mazda 626LX 2.0L's (only 35k on the car) horn went off all by itself at 2:00AM on the 4th of July. I was fast asleep in the house, got a call from a neighbor telling me my car's horn was sounding. I was actually relieved because being the 4th of July in an urban setting, I was instinctively nervous that he was going to tell me that my house was on fire!! Disconnected the battery and got a few more hours sleep. When light outside I reconnected the battery and the horn was not sounding. Now, 11 days later no evident problem, but of course I have to wonder if the horn just won't go on by itself, so I stashed a socket set and pliers in the car so I can disconnect the battery or pull off the horn relay in short order. The Crime Guard car alarm has been iffy for a few years. Sometimes it works and other times it does not, just a head scratcher. Seems unrelated to the horn problem (the car alarm does not use the horn but a separate speaker-like affair, it's one of those sing-song all over the place alarms), but who knows?

2001 cadillac deville dhs..Took my fuse off kept going for a bit the shut off on it own do I still check my relay?

I have a quick question my 2014 ford fusion horn goes off by its self at any given time even when the keys are not in the car (happened twice that I can remember). any suggestions

I have an air horn that once in a while doesn’t come on. I sprayed the horn with WD40 and got it to work. I had previously put in a new relay and fuse. The shop that originally installed it said it was the clock spring but I read a tip online about the WD40 fix.

Thanks 👍
