First, have you tested the shifter actuator @ the transfer case ? It has been my experience that this has most often been the problem. This part being both mechanical and electrical is pricey,have it tested first,but in my experience this has been the culprit 95% of the time.

would that be the same as transfer case shift motor & how would i test it ?

Yes, removal on a scale of 1-10 for the mechanically inclined in my opinion woulb be a 3, so simply remove it ,actuate your switch to test for proper operation. I have found most often that they stick in one position or the other.
