Possibly loose ground connection. Check horn wires for both positive and ground when horn is pressed.

When you press the horn pad on the steering wheel a "horn request" signal is sent to the BCM (Body Control Module). The body control module then sounds the horn by completing the circuit to ground. Could be a BCM problem. Are any other accessories not working? HTH. -Jim
