Evening
Guess there’s a solution somewhere before.
Neither horn button works on my 1999 MV6.
It used to but not anymore.
Changed the relay twice for 2 spares, fuse fine + swapped it just in case, tapped horns under car a few times to jiggle them into life and felt around the wiring which all seems secure under NS front.
Only thing I’ve not done is remove airbag and check condition of button electrics - but neither work.
Also the there’s no vibration/click from relay if you hold it whilst depressing horn buttons.
Other than check the button electrics is there anything else ?
I’ve not removed horns nor tried a direct feed to them but on my radar to do unless something daft
