Horn will not stop blowing

Could be the horn relay sticking or the horn button circuit is shorted out
Looks like fuse 43 is strictly for the horn, you could pull it, if that causes other things to not work, pull the horn relay

See the diagram below for fuse/relay locations and full wiring diagram

My horn goes off at night and wont stop until you disconnect the battery. Is there a horn relay or a sensor that needs to be replaced?

hi, there should be a horn relay, underhood fuse box, unplugging the relay should kill the horn. I'd have all trouble-codes checked. Your theft system could set off the horn, problem with horn switch and wiring circuits?

Hello, i am having a problem with the horn in my car. The brass ring that makes activates the horn is damaged and i rather not replace it because of the work involved. I heard some people have bypassed the steering column and have wired the horn to a push button, which i do not mind doing. I know what color the horn wire is, i just do not know the exact wire in the steering wheel column. There are 2 black wires in the steering column, i just dont know which of the 2 is the horn wire.

The problem with dealing with the steering column is that there is always a chance that you could accidently deploy the airbag.

I would get a horn from an autoparts store and wire it in seperatly.

HORN WON'T STOP BLOWING

Pull horn connector to stop it, but it is either a stuck relay or horn button.

Quickly touch the horn relay, if it is warm/hot then most likely the relay.
