Ran truck into snow drift recently, spent half an hour rocking back and forth in 4W-Auto while waiting for tow (never revved past 2500 rpm, didn't really strain anything). Winched me out easily enough, left truck in 4W_auto but put tranny in neutral, only pulled me backwards a few feet to get out of the drift. Since then, no 4WD. No lights on 4WD switches on dash, blown ATC fuse.
A "friend of a friend" hooked up a code reader which reported that it couldn't communicate with the transfer case encoder motor.
Most likely replace the encoder motor?
