cant get the 4lo to disengage back to 2hi
some ice must have punched the mechanism once or twice...look at the motorized goodie near the transfer case to see if the motor is turning there~...take a look at the fuse/relay then if it ain't turnin'~ could be a connector come un-connected~
The transfer case motor is stuck. It will need replaced. Had one yesterday doing the same thing.
