First Mini Cooper,
2015 convertible. Horn doesn’t work. Assumed it was the horns so bought new Hellas and still nothing..
Don’t know how to test for power. Is there a horn relay in passenger fuse box?
car has 100k on it.

 

Anyone please can anyone offer any help?

 

Have you tried changing the horn fuse? Just because it looks good, doesn't mean it is good.

 

I switched the fuse with another working circuit

 

I wonder if these are contacts that need sanded for proper contact to sound horn…I know this is a problem with newer minis 2016 and up

 

I have sanded the contacts, replaced the fuse, replaced the clock spring, tested the horns.

I JUST NEED TO FIND THE RELAY, it looks like on the r56 it is behind some of the passenger footwell fuse boxes but does not appear to be the case for r57, I see no fuses on the back side of that fuse panel.

Could anyone please point me in the direction of the relay?

 

I did the same then searched for relay and think it’s built into wiring harness. No removable relay that I’m aware of, that’s why I bought a wireless component to use a button provided to use horn…I was also told from other findings thst the dealers replace the steering wheel for repair
