i had the same issue a couple months back and it ended up being that blend door (heat) was stuck in the cold position. removed dash played around with actuator it started working. 3 days later same thing. pulled dash again replaced actuator no issues since. Also found actuator that selects floor, top, dash was not aligned and one of the little nipples was actually completely out of the track. fixed that all in one shot. If you have big hands like me, and no wife/gf that can help, take it to a shop.

I'm so happy it wasn't really cold this morning in ATL, because this happened again on the school run. Set it to 90* and it was still blowing cold, so I ran it off and on just to keep the windshield from fogging up. When I got home, I took the valve's cover off and removed the gear & screw / shaft. I tried to open the valve with the gear by hand and couldn't. Grabbed a pair of needle nose pliers and it turned a full 1/4 turn, and the truck immediately had heat. Given that even in hot, Georgia summers we've been having to turn it up to 80 to keep things comfortable this year, I think we'll be ok. If not, I have all the parts put in a safe place, just to make sure I can never find them again
