I think that flap varies the ratio of alleged 'fresh' Vs recirc depending on
temps, etc, and the only time it remains fully closed (recirc) is on MAX
A/C. (?)

There's a door above and behind the glovebox that lets cabin air get to the
fresh air intake when the air conditioner is on.  It is closed for heater
operation.  Yours probably is open, meaning warm cabin air gets mixed in
with the air supply going to the heater core,  resulting in very moist air
back into the cabin.  It's probably open because the spring that holds it
closed has cut through the plastic bar to which it mounts inside the HVAC
evaporator box.  If you put your head in the footwell and look up past the
back of the glovebox, you may be able to see the door.  The fix is to put
something in there to hold the spring.  Most use a piece of tin formed
around the bar.  Some have used zip-ties to make an anchor for the
spring.  I had to take out the glovebox to have enough elbow room to get
it  fixed.
