My IP center stack on my '03 Discovery had a nasty crack in it from the PO, so I ordered a new one from the dealer. Got it and installed it...noticed something odd. When the lever is to the left (blue dot), the vent is closed and to the right (white dot) it's open...opposite of what the manual says it should be and opposite of what is the case with the outer IP air vents. Took it all back out and checked to see if the levers were swapped by mistake, but no way that would work. Has anyone else had this experience?
