Hey folks, opened up my door and noticed there's a decent amount of dust in there. Where is it coming from? Is it time to replace the rubber seals around the door?

Also what's the story with that white plastic thing, the vapour barrier? What purpose does it serve?

Door skins are not fully sealed from the elements. If you look closely there are small holes at the bottom of the door to allow moisture and water to drain. The plastic vapor barrier works to keep dust/water from entering into the actual cabin/prevent the door cards from damage.

Hope this helps.

Zanethan is 100% correct.

Our doors are not sealed units. Fine particles of dust will enter around the window seals by the wind and rain. Additionally the drains built into the bottom of the doors allow another access point for which dust will enter.
