At highway speed I get a breeze from all open vents (with the blower off), especially from the center ones. Is this how you guys have it too? If in doubt just stick your hand in front of each vent. I wonder if there's a flap behind the glove compartment box or somewhere that's supposed to restrict air from coming in and it's not working. Does anyone know?
