Why is my Horn not working at all.
Horn does not work when you press on it or does
not work when you press key fob to lock car.
Check the fuse, if fuse is ok, check the wire going to the horn and make surr it's mounted on a clean place to get good ground. If everything looks ok, check voltage at the horn plug when u activate the horn. If voltage is present and still doesn't work, replace horn.
Fuse is good, has new horn relay.
