the second day I had mine the yellow light next to 2WD turned off. None of the lights would turn on and it wouldn't go to 4HI or 4LO. I parked and turned off. About an hour later I got back in and cycled from 2-4hi-4lo and turned off again. When I turned back on the light was back on 2WD and I could cycle between 4hi and 4 lo. It hasn't done it since...
