Technical Seicento horn

[twig101]

Hi everyone,
Girlfriends car went for mot last week and failed on a few things, bushes, brakes, horn.

Been working my bum off on sunday to replace bushes, brakes etc.
Saved the horn till last thinking it might just be an easy fix.

Doesnt appear to be that way,
Tested reading at horn and get nothing.
Put a 12v supply just to check horn and that seems fine.

Check reading at horn buttons when pressed and they seem fine.
Swapped a few relays around and fuses just to see if that could be it but still nothing.

Anyone any ideas?

Any help is appreciated

Maybe a short in the wiring between the two or a dirty contact. Not sure if the horn uses the boss ring. I know the airbag does.

did you disconnect the horn and checked that power arrives to the connector?

the 2 connectors that attach to the horn are the problem cut them off and take about half inch of wire off as this corrodes as well and then just put 2 new spade connectors on and reconnect job done.....same problem with all of my cinqs
