Mine has a large door that blocks off the fresh air from going thru the heater core. Most of the similar heaters that I've seen in videos and in pictures do not have this door. It seems to me that it served a pretty important function. Did some of them come without this door, or do lots of people remove them. If people do remove them, why do they do it?
