Horn not working

[marc]

Installed a light bar in my grill and relocated my stock horn. Now my horn doesn't work when I hit it on the steering wheel but my panic button works. All connections are good and fuse is also good. Any ideas? Thanks.

might check your ground, did you remount them to a plastic piece.

Second on the ground. Most likely problem. Jump voltage from a battery straight to the horn power. See if you get honk.
