Help!
Despite 2 professional interventions, my horn is now out of order. No sound. Before it was working even it was a bit tough.
I suspect either a dead fuse or a disconnection somewhere.
I've 2 questions:
- which fuse is governing the horn and with what other device(s)? I can't see any mention on the fuse panel.
- where is situated the horn? Close to the starter? Elsewhere?
Thanks a lot.

The P5B, not sure about the P5, has two horns, one high tone and one low.
Best way to find them is go to the front of the car and look at the front valance under the bumper. You will see two oval holes in the lower part of the valance. the two horns can be seen inside these holes in the valance panel.
Mine only worked intermittently then stopped completely. Could never get them to work reliably from the horn ring so I fitted a bypass switch and installed it under the front parcel shelf, from where the horns could be operated. Have to have another go at sorting it properly now the bypass has been disconnected to remove the engine and trans.

I've seen them but it's rather low for my backbone (I've got the Modic disease) and I've no elevator.
I'll give it to the mechanic hoping this time should be the one...
But you're not the first one to tell that those horns look cyclothymic...

The battery control fuse which powers the clock and interior lights also supplies the horns (via a relay on P5s) Apart from poor earths and connections the horn ring contacts in including the central earth return bullet may need attention. The contacts in the horns themselves may also be tarnished. Bypassing the horn ring and earthing the horns direct will test them

I've ordered the UniTacho from Mark Willows since Chris (Spiyda) doesn't want to answer my questions, which is a real disgrace... Hence when I get it my good man (my previous mechanic since 2015) will do the job as well as solving the horn problem since the second mechanic (who has done a brilliant job on the carbs and some more nevertheless) doesn't want to answer... You can judge the value of those guys on how they treat you when tricky problems are happening...  |

As I was fed up with that nasty horn and my mechanic isn't available, I took off the horn ring myself because the problem is at the wheel.
A bit harsh to slacken stuck and corroded allen bolts : I did it with WD40 and a torx key because at the umpteenth attempt the hole was a bit loose. Moreover it's not very obvious to adjust the three bolts when you don't know what to do and don't understand exactly whether to tighten or to loosen the springs. But now it works at last nearly 100%. I assume that the contact is a bit fiddly and looking like working at random but it's far better than before because in the end after two so called interventions supposed to cure the problem by the second mechanic at Montauban it was no longer working!
