My recirc door broke and I took it out until I could get the part does this mean I will have only fresh air or only recirc air? Thanks

 

You would think the easiest route for the air would be recirculating, and I'm pretty sure most of it does recirc, but when you pass by a cattle stock yard, you will find out you do get enough "Fresh" air, you wished you turned the air off before you got there.

 

with the door gone you will only have fresh air the door closes the outside air out.
