Hi my name is ***** ***** I will be happy to assist with this today.Code c0321 indicates a fault with the transfer case lock circuit (transfer case actuator circuit).code c0392 indicates a fault with the transfer case actuator rotation circuit.
C0396 and c0398 is an internal switch fault in the transfer case actuator.
with what you have described here with what occurred and the codes set here this sounds like an internal electrical fault in the transfer case shift actuator itself on the transfer case needing replaced.I have had to replace this actuator before several times for this fault here.
Let me know if you need anything else and feel free to rate my help here.
