HVAC comb flap behavior
Went on a little trip, and noticed that after a couple of hours on the road running the AC, the comb flap (I think) would close, preventing strong airflow from the center vent.
Verified this was not due to a vacuum issue; I already fixed that problem.
It appeared to be due to the system thinking, perhaps falsely, that the interior had reached a target temperature. The only way I could get the comb flap to reopen was by turning on the rear AC. That worked every time. This seems like odd behavior to me.

Min temp override (e.g. temp slider all the way to the left) should get you comb flap to heater core bypass always. If it doesn't - you have a problem.
