So I'm driving to work this morning in 4Hi since we had snow yesterday. The truck was already in 4Hi from last night. Roads started to clear up so I decided to switch into 2wd, and the rotary switch won't budge, it's stuck on the 4Hi setting. It's like something has locked the switch from turning in that direction. I was able to switch into 4Lo (at a stop of course), and back into 4Hi, but it wouldn't go into 2wd. I tried a little reverse, still nothing. Then a little further down the road I made a left hand turn and tried the switch again, no problem, switched right over into 2wd. I thought this was really odd, maybe coincidental?. Has anyone else had this happen, and if so what was it? I had no errors with the dash lights either. I'll try it again when I leave work to see if it's back to normal.
