So, I have been living with a frosty cab because it's better than blocking off the radiator and loosing the benefit of the intercooler, but yesterday, bling! I had heat. The temp needle moved up to it's normal position! I have had good cab heat since then.... I guess the thermostat was never closing all the way THE WHOLE TIME I HAVE OWNED THE TRUCK! It always worked fine when it was warmer, and when I would block it off the temp would eventually come up to normal after it got a little warmer. I just assumed it was a diesel thing. I actually had to turn the heat DOWN this morning!!!

I'm at 7,000 ft elevation, and we recently had 3' of snow on the ground. It's been well below zero many times already. We haven't seen 70* in a long time!
