Decided to put the truck in low gear this weekend to make sure it still works. Have not been offroading for a few months. It was a bit difficult but finally engaged and I drove it that way around the block in 2nd gear. Seemed to run fine, and was equaly difficult to get back into high gear but I prevailed. That said the A/C shut itself off while I was in low? Came back on in high after I turned the truck off and back on. A/C ran fine again in high today on the way to work? Should I just ignore it or is this a common bug? thx.

 

Shifting the t-case had nothing to do with it.
Could be a bad fan speed switch, could be a fluke.
