R34 GTT Horn not working, fuse is fine

[r34ttg]

Hi

I bought a pair of used Ford Falcon horns intending to replace my current horn however the ford horns i installed didn't work so i put in back my old 34 horns and to my surprise they did not work as well.

I checked the horn fuse and they are still intact. When i push the horn on the steering wheel, the horn relay makes a clicking sound so its not the relay.

Any more ideas?

Sure you've got the wiring right? Check if the relay trigger is getting power from the horn button or (more likely) earthing through the horn button. If you can hear the relay clicking you most likely have a wiring error.

Just because a relay clicks doesn't mean it is working.
