New to the forum. I been reading about the service 4WD error message in the DIC and determined it was the sensor in the transfer case position sensor which I replaced. I did test the switch in the dash first using a dandy youtube video explaining the ohm reading per the switch selection and all the readings were in ohm range. I was excited to finally not have the error message but after the sensor replacement the error came back almost immediately. Question I have is I think it only can be 2 things. Either I have to replace the whole sensor motor unit or possibly the switch is still no good, maybe I didn't test it right? Anyone have any ideas? Important to note that I have no issues with driving it slipping out of 2WD but occasionally I have trouble getting it into 4WD
