I have an 05 regular Mini Cooper, and today the horn just randomly died. It won't honk or make any sound at all. Has anyone else had this happen to them? Does anyone know how to possibly fix it or what may be the cause?

 

May it RIP. Have you check the fuses and relays?

 

I checked the fuses and they're all still good. Where are the relays?

 

Under the hood there is another fuse panel with relays.

 

I have the same issue with my 05, but it didn't totally died it just went from loud to weak sound after a rainy day, I checked the fuse and it's fine however I did not check the relay or know what to tell if is bad.
I was getting ready to order a new horn until I saw that they have two kinds, low tone and loud tone. Do we have two horns or one? I saw a pix of a MINI with 2 horns so I'm not sure what to order. Thanks in advance for any imput and to the OP for posting.

 

You have two horns. One low tone and one high. They are located by each front turn signal indicator as seen in this picture.

 

great, Thanks Braminator, it appears that the horn that is working for me is the one on the driver's side the other (Passanger) side is not working. Thanks again

 

Glad I could help out.

 

Mine half died sometime over the weekend. We got rain, and I blew through a couple puddles, and now it sounds very anemic and wheezy.

Looks like I will need to find some $$$ to get the Hellas, since they don't appear to be able to collect water....

Too bad I can't get the little horn from The Mask, the one he pulls out of his pocket and blasts the honking car with. That thing rocked.... :D

I had hoped to see a joke about horn broken, using middle finger instead.

 

One quick test is to use a test light/multimeter, disconnect the faulty horn and plug the test light/multimeter in the plug and on a good ground. Press the horn, if the test light comes on or you get voltage (whatever the battery voltage is), you know that everything from the fuse, steering and wiring is ok and that the horn is dead.

It will most likely be the horn. You can also test it on its own by jumping it directly to the battery, but if it start working, it might scares the living hell out of you :p

 

When I dismounted the horns, both dribbled some water out. I guess they're in a spot where they can get water in them if driving through a big puddle. We got rain last Saturday for the first time in months, and I drove through a few puddles....

New horns courtesy of O'Reilly Auto Parts fit nicely, and don't have the snailshell design like the originals, but are a disk similar to the horn on an old air-cooled VW. There are separate low and high notes, and, as a bonus, instead of sounding like a Buick (my biggest gripes with the MINI were the Buick-y horn and the very approximate nature of the resume feature on the cruise control), it actually sounds like a European car's horn ought to. Ironically, the Buick-y horns are made in Italy, and the Euro-y horns are made in China....
