Drove wife to work in the morning after it snowed overnight. Didn’t need 4wd to get around. Later this evening she got a ride home so after it dumped another maybe 7 inches, I went to turn it around in the driveway. Almost got stuck. Switched to 4wd, said was in 4wd, continued in reverse, was not in 4wd. Service 4wd came on. Switched to drive and felt it kick in 4wd. Backed in to my spot, stuck in 4wd. Had this happen before. Shut off for a min. Turned back on switched to 2wd and I felt it unbind and shift out. Then I cycled back and forth a few and it was working. Any of you have this situation?
