A/C & Heat Ventilation ???

[apichartv]

Hi, Need some help to identify this picture, not sure what is it. Should it be left open or close.
FYI, I am replacing the blower for the a/c and heat for my 2000 Boxster and see this opening near by the blower.
Thanks for any input.

Please resize the pic. It's waaaaay too small.
