99 nbs. When it first shifted i got service 4wd light amd no lights on the switch. I shut the truck off and started it again, 4lo light is on and the tcase is in 4lo. I push the 2hi button, it flashes, i hear the encoder motor try to make the switch twice but it fails every time. Its my dd and I need to get to work in the moring. How can i get it back in 2 or atleast in 4 so i can atleast drive it tomorrow and work on it after work?
