Check #17 under the hood. Should be a 30 amp maxi fuse.

Had a similar issue recently ended up being a broke wire going to the gem module. Had a local shop test the wires as I don't have the patience. I would start with the transfer case motor to make sure it is good, then go from there. Sorry for not being more help just my experience. They spent two days ohm testing every wire and only charged me 200 for the repair. In my book that's 150 less then the gem module that the dealer swore was the problem.
