It is very close to my expereince. If I have any of them partially closed, then it dominos. First one, then another, then .... until they are all closed. Once the first goes, then the rest goes quickly.RacerZX wrote:Hm, that's a new one for me. I just went out to the parking lot and played around with it.
It appears that the blower feeds all 4 vents, so if I have 3 of them closed the air force out the last one is quite substantial, and if I have that vent in the, say roughly, 66% closed range, it'll snap closed by it's self. However as long as I've got one vent wide open, the pressure isn't enough to close any of the other vents even if just open a crack.
How does that compare with your expiriance?
