Much more fundamentally, if the selector switch has ZERO lights on it, the TCCM isn't running. Could be a simple fuse issue. Start by checking fuse #8 under the hood. Once you have lights on the selector switch, THEN you can listen to see if you hear the expected noises from the front axle actuator and the transfer case encoder motor.
