Horn Will Not Turn Off

My 2017 silverado horn keeps going off I replaced the junction box and the clock spring and it won't stop unless I take out the fuse

You can do a simple test - With the keys out of the ignition, unplug the brown connector from the BCM. The BCM is right behind the floor brake pedal, its a black box with 7 coloured connectors.

With the brown connector unplugged, reinstall your horn fuse, F48.

IF your horn still blares non-stop, you most likely have a bad relay. If the horn does not blast, you could have a bad BCM output, or, you could have a bad clockspring/horn button.

Since you've already replaced the fuse box and the clockspring, try whats written above. If the horn does not sound after removing the brown BCM plug it is most likely your horn button in the steering wheel airbag.
