2016 2500 SLT, Cummins, I have a similar issue my horn stopped working at the same time the EVIC- Electronic Vehicle Information Center quit registering current information. Dealership quoted $1900.00 to replace the Clockspring. Sounded dubious at the time. Didn't know it could effect the airbag!

During a problem with Lights on , horn and A/c would not work. Lights off only horn or A/c would work, not both. Turned out the short was found in the computer for our truck. We redesigned the horn to another circuit. Created a new ground for horn to fix. The mother board for the trucks computer is not available. Going to repair the mb and sauder the circuit hoping it works. Your truck is newer but a quick look at the computer board will be obvious if that's gone bad. Our s was right side by hood hinges.

Start at horn, with a volt meter , if no 12v, check in fuse box, and see if there is voltage at that fuse both sides, when someone hits the horn . If you hear a relay, you should fell it click if you put a finger on it.
I would think there is a connector at steering column for the horn as well as all the other stuff.
I would hunt up a wiring diagram and check the clock spring with a ohm meter .
I had one a part , but it was yrs ago on a 1990's Dakota , would be a lot less stuff to mess with.

I just watched Rainman Ray change a clock spring in the interweb on a car.
Did not look too hard.
Check the wiring as well

Also, it seems like the first thing to do is reseat all the fuses and relays, a wack sometimes can help

Any update on this? The horn button, along with all the other controls on the steering wheel, go through the right switch assy. Then the right switch assy converts all the signals and sends them out on a LIN bus line to the clock spring. The clock spring takes the LIN bus commands and converts them to CAN bus and sends them to the BCM. Currently, I'm chasing an intermittent horn, and it appears to be leading me to the right switch assy, as everything else works, and the horn switch assy in the steering wheel is brand new, and I verified its operation after installing it.
