The horn on most vehicles is switched on the negative...

So the horn will have a 12v feed to it, then the other connection makes it way to the steering wheel, and is grounded when you press the horn switch.

So you either have a chafed/damaged wire at the steering wheel , or that wire from the horn is somewhere accidently being shorted to 0V
