I know the battery heater is likely to turn on if battery temp is below about 70 degrees. Could it have been that?

The other silly thing about the Bolt is it uses resistive heating elements for hot air, but still utilizes a liquid heat exchanger (heater core). Instead of just warming the air directly and getting instant heat, they added complexity. Heater cores are the bane of HVAC, just ask Xist.
This is similar to the volt, especially if auto defog is enabled, it’s very humid and eco or comfort is selected.

Hard to disable without running fans and keeping the temp down
