Just a random theory based on my limited HVAC knowledge.

Interesting... I was under the impression that the 240D did not have vacuum in the HVAC controls though. That may be wrong.
Thing with the air not entering is that this system blows great under heat and AC. Id think that I would hear a restriction, or feel reduced airflow. The system blows!
But your point is one well taken, that Ill have to look into, thanks!
