Hi my name is ***** ***** I will be happy to assist with this here.
From what you have described this sounds like an internal electrical fault with the transfer case actuator as this can be common needing replaced.I have also seen issues with the transfer case computer/control unit needing replaced.This will need tested/diagnosed further to be sure one of these is the cause having the fault codes read out to help diagnose and repair this issue.
Let me know if you need anything else and feel free to rate my help.
