Repair. How to fix any other suggestions
Lightly tap on the transfer case shift motor while some pushes the 2 WD button, this might shock the motor to work one more time. This should be done on flat level ground with the trans in nuetral, key on and blocked so it won't roll. If it won't run then you have to take it off and manually put it into 2 WD. Then you can check the circuits out and replace the motor assembly later on.
