Thanks for the heads-up on the HVAC TSB!
I've complained to my dealer all winter about the wussy AC unit. It's never been disconnected, and it runs constantly since I nearly always use defrost mode.
Most of the time, passengers in the rear seats cannot see out of the windows at all. I've got the deep dish
floor mats, and really make an effort to keep excess moisture out of the cab. It really is pathetic that an expensive truck would come with such a pansy climate control.
