>>>>FIRST disable the air bag system
You'll need to remove the upper and lower steering column covers.
Also all the trim under the drivers side, kneee bolster, etc...
The ignition switch has 2 screws holding it on.
Remove those screws and all related wiring harness.
Then the switch.
Here is the procedure from GM......

Place the multifunction lever in the center or the OFF position.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Disconnect the battery negative cable.
Disable the SIR system.
Remove the steering wheel inflator module.
Remove the horn plunger contact.
Remove the steering wheel.
Remove the tilt wheel lever.
Remove the ignition lock cylinder. Remove the upper steering column trim cover.
Couldnt find a diagram. Hope this helps.
