Probably something else. These are connected via wiring from them down the inside of the steering column to a connector at the bottom. There will probably be a problem at the connector or in the wiring in the column or from the connector on to the BCM.
Is the air bag light lit on the instrument cluster ? Could be the clock spring . All the switches on the steering wheel go through the clock spring .

I have a 2013 xts Cadillac...The first thing I notice was steering wheel light started blinking.about week later the went completely out. Then the cue radio touch went out. Could this be a clock spring?

Replace the clock spring, or check all the cabling and plugs first. If you are inexperienced take it to an auto electrician, otherwise do it yourself but disconnect the negative battery terminal for 2 minutes prior to opening the steering wheel to check the plugs, as not doing so could cause the airbag to go off. In addition you can also take out the airbag fuse. Check radio control plugs and close it up again and reconnect everything in reverse order. If that doesn't fix it, then have the clock spring replaced professionally, its too much mucking around if you don't know what you're doing.

THIS IS A RADIO PROBLEM, THIS PROBLEM WILL REQUIRE THE RADIO BEING SENT OUT TO AN AUTHORIZED FACTORY ELECTRONICS REPAIR CENTER, THERE IS NO BLOWN FUSE OR THE RADIO WOULD NOT EVEN TURN ON.

Replace the Clock spring. It is mounted behind steering wheel. It alows electrical connection while the wheel turns.

The lights on the steering wheel are in the switches. To fix the lights, the whole switch needs to be replaced. Same thing goes for the Tempature Controls and radio. Overall, I think it would be very expensive to replace all of the switches to get the lights working. I have the same vehicle, and almost all of the lights are out.
I think the lights behind the gage controls are replaceable, although you still have to rip out most of the dash to get to them.
I have the auto-sense wipers, so I was leaving the wipers on all the time, and the would only work when needed. The bad part I finally found out about this was that while the wiper switch is on (even though they were not wiping), it caused all of the dash lights, switch lights and rear parking light to be on. I think this alone significantly cut down on the life of the bulb.
For now, I am just living without the lights. The temperature control is very expensive (just the part alone).
