Vent door behind glovebox...

[Bob Mansker <oscargum@datasync.com>]

Doing my Sunday Audi repairs & making the Adui gods mad at me so far.
Found much leaves behind the Vent door behind the glove box.
Also have a vacum line going inside (through the door seal) which seems
unlogical.
This vacum line comes from the A/C control unit behind the glove box.
Questions:
        Why is there leaves behind this door?
        Should the vacum line coming from the A/C unit be going into the
door opening??
Thanks for all your help.
I am trying to get my center vents to open.
