I got the no name OTA last week, which was a BCM update. During two of the three times I've driven the truck since then, it has started blowing cold air out of nowhere. No changes made by me to the controls, and not a situation where it might fluctuate between A/C and heat. Wondering if it's tied to the OTA.

Coolant levels are normal.
