Starting this morning I can't get my 2006 Silverado 4x4 transfer case to go in to Neutral. Normally this would not be a problem, but we tow this truck behind our RV.
I looked for a fuse, but did not find something obvious. It will go in to 2 WD, 4WD high, 4WD low, but not Neutral. I've always pressed the 2WD and 4WD High together to shift in to Neutral, but this does not work anymore.

Any suggestions?

Thanks,
Bill
