Any idea what thats for? I looked at it and it doesn't really seem to have a purpose. The flaps push away from the trunk towards the outside but I had to actually push them with my finger to get them to move. They don't look like they'd move from air pressure alone. Wondering if that could be where I'm getting my problem from and if I could just block the whole thing off.

 

None. I figured it was some vent or something for the trunk area?

 

Yea I mean thats what it looks like but I have no idea why the trunk would need a vent. If thats where the problem is coming from I'm just going to block it off, doesn't seem like it'd be a big deal.
