Having a nightmare where the horn was sounding non stop.
So I pulled the fuse out until I could get round to looking at it.
I put the fuse back in today and it doesn't work at all now.
I have looked at the wiring diagram and it shows the horn relay as R14.
I have looked everywhere for it but I can't find it.
I've looked everywhere online and only things I can find are for the x350.
I would be most grateful if one of you knowledgeable guys can point me in the right direction.
Thanks

 

It would be better if you identified the details of your car year, model and engine. However the relay is likely in the engine compartment junction box, likely under the fuse rack and maybe unreachable. You can test the relay by checking the voltage on both sides of the fuse using a voltmeter. You will need someone to switch the ignition on and activate the horn button while you check the voltages. No voltage and the relay is suspect. .

 

I've swapped the under bonnet fuse/relay box with the one off my wife's car and it works perfectly well.
these don't need to be coded and relay R14 is soldered onto the internal board for anyone else trying to locate it 😊
