Hello, all,
My horn had been working normally, and now it does not. I checked the fuse (F8 in the under-hood panel) and it was good, but I replaced it with a new one just to verify. Still no horn. I've read through a bunch of other threads on this site and can't find a solution. Everything else on the steering wheel still works as it did before the horn failed, so I don't know where else to look. Is there another fuse that could also control the horn circuit?
Any suggestions for trouble shooting would be greatly appreciated.
Thanks in advance,
Gerry

Re: Horn not working

Re: Horn not working
Thanks for your reply, Steve. My car is a 2013 9C3. I'll check for a broken wire, although I can't understand how that could happen. The horn was working fine.

Re: Horn not working
Is there more than one fuse controlling the horn? Any relays?
Thanks again,

Re: Horn not working
Steve, thanks again. I found the relay, it's R16 in my 2013 fuse panel. I checked it and it's good. However, I dug around under the glove box and found a pair of wires that had become disconnected from a butt connector. I cut out the connector and replaced it with a good one, and used some good crimpers to re-make the connection.smwalker wrote: ↑Mon Oct 04, 2021 4:47 pm Yes fuse and relay controlled by the BCM both model years:

Now, I have a horn again.
Thanks to everyone else who helped on this.
