4WD will not disengage on 2000 Chevrolet Silverado 1500

My truck will not come out of 4WD back into 2WD. My indicator lights do not light up for 2WD or even 4LO. I cannot get the truck to transfer into neutral either. It is in 4WD and there is no more snow!

I would get the diagnostic codes checked, it's possible the transfer case shift control switch has failed, but a diagnosis should reveal that.
