Clunk <penny dropping> :) I followed a -3- hose over to the RHS of the dash as well, so I was very confused about what it did. I seemed to simply run from one side to the other. There'll actually be two hoses labelled -3- going to each of the end vents. I do remember that one of the vac lines on the vent controller cluster went to a Y junction - that'll be the one that serves both of these vents. I never use the LHS (passenger side for me), so I'd never notice the difference. Perhaps I will now that I know it works. This actuator is somewhat bigger than the fresh air flap actuator under the bonnet. My current 900 does not have a fresh air flap, but my first one did. Can they be retro-fitted? I still have the button from my first one :) I like having re-circ, especially when following smelly diesels or driving past landfill sites in the height of summer. Thanks Dave (and Grunff). I'm enlightened. Paul
