Fresh/Recirc Blend Door Actuator?
Had the AC on today cranking on high (setting 5) and set to fresh when suddenly the fan got louder and blew harder as though it switched to recirc on it's own...which it did. Pretty sure this has happened before too now that I think about it. I switched it to recirc myself by hitting the button and confirmed that it was already there by the sound and power of the blower not changing. Switching back to fresh didn't change it either. I shut off the truck and went to the store and afterward it was functioning normally. I know that the blend door actuators can be problematic, but I've also heard of something called "auto recirculate", which my truck may or may not have. Any ideas?

Mine is screwed and stuck, throwing a code B0229 if I remember correctly. Such a PITA to fix that I've just been putting it off, it could be that it was trying to cool the interior down due to heat. Been a while since mine worked right.

Seems like these buggers are more common than I even thought. If the actuator does need replacement it will have to take a back seat to the other small list of annoying repairs that I have to do first lol.
Thanks for the replies guys!
