Is it going out via the door seals (my guess)? I can't see any designed way out for the pressurized air from either cabin heat or overhead cooling vents. Methinks that air pressurized for heating the cabin is better than recirculated air as it floods any possible air leaks into the cabin with the heated air. However as there is no designed vent or dump of the pressurized air, is this situation best for our door seals and/or where ever else the pressurized air exits the cabin.
