Classic transfer case shift motor failure, have someone push the 2WD button while you lightly tap on the motor with a small hammer, if the motor runs and get you into 2WD then you have found your problem so replace the motor assembly, if it doesn't run then you will have to check for power from the GEM unit to the shift motor, just hope you don't have to go that far as you really have to know what wire is for what mode so a wiring diagram is a must.
