4WD suddenly won't disengage

[LadyJane]

I have a 2019 2500 Big Horn. Today suddenly the 4WD wouldn't disengage. The lights on the switch that show 2WD, 4WD High and Low won't come on either. I am thinking possibly a blown fuse. Any one else encountered this issue?

I did once. Complete stop park, turn off and on truck then put in Neutral and try to switch again.

Make sure wheels are straight too.

Thanks. I should have thought to shut it off and retry but was in the middle of hauling. Will see what it does in the morning. Thanks.

I had mine go dead on me in 2WD. Then it cured itself. Dealership reflashed it. No problem since, and it has been in and out of 4WD a few times.

Sounds good. Good luck.
