Transfer case shift motors are a high fail item. Try lightly tapping on it while someone switches it into different modes and see if it runs. If it does you forums your problem. If it doesn’t then you need to run circuitry testing from the module to the shift motor. Note, there has been some problems with the wiring harness right where it comes through the floor to the transfer case, the wires have been flex breaking. Also check the grounds.
