Read a million posts on problems with SERVICE 4WD and finally found one like mine. There is a sensor on the front output shaft, no doubt tells the TCCM that 4WD actually engaged and output shaft is turning. Guess I'll clean the snow of the truck and pull it in the garage. Maybe it's something simple like loose or corroded connection.
You wouldn't believe all the problems with bad dash switches and TCCM connections. Hopefully my problem is at the sensor and not the TCCM, it's located behind the passenger kick panel.
