Horn on door lock malfunction

[dnme305]

Hey has anyone had an issue with the horn not sounding when hitting the lock button twice on 07+ Tahoe?

All of a sudden from one day to the next it is not working. I confirmed on the dash screen that it is still activated. Any help appreciated thanks

Mine wont honk if there's still a door open or cracked. Maybe you had a door ajar or the rear glass popped?
