horn not working

[hammer]

hi horn not working on my 2001 transit tested wire at s/sheel with test lamp there is power but it very week it just about lights up test lamp dose it run with a relay if so wher can i find it thanks hammer

iirc horn push on steering wheel on most cars is an earth not a feed so will show low power if horn dead , you need to test the wires at the horn and see if one is live all the time , other will be an earth when horn push is pressed and no circuit when not

horn ray in engine bay fusebox, get someone to push horn button while you listen for relay clicking, usually horn itself that fails
