[V6-12v] Evaporator flap

[Kiryl Mauryshchau]

After removing my heater box, something came out from the evaporator
opening. It looks like some kinda flap, yellow color, plastic. I figured
that it is controlled by the flap motor to open/close connection between
evaporator and heater box. My question is - when I'm going to put it back,
how do i have to turn it? in what position? Thanks.
