    Blue lever up = closed off , fresh air.......down = fresh air in via round outlets at each end of the dash and via the vent slits that feed the windscreen.
    Left hand red lever directs hot air........stay with it !.....down = up through the dash slits to delist the windscreen.
    Left hand red lever up, directs hot air to your toes.
    Right hand red lever determines how hot the air will be.....it controls the air that flows through the heater boxes.
    Right hand lever all the way down contacts a booster fan that keeps the air flowing when the engine is at low revs....

    Those diagrams don’t look like a T2 setup Grant......
    Where are they from?
    Caveat .....mine is an Oz assembled T2, so may differ from German builds....

    Should have said, that’s what the German built ones looked like when they the factory in Germany.

    Came from a handy reference site we use for the T3’s.... as the diagrams on the T3 pages, are exactly what the the fully imported T3’s do look like. ;)

    Pictures are for LHD and shows most variations through the years,
    Bottom photo is of early bay period.
    Middle is about discussion above
    Top is of the door vents through the years and the connections on either side of the door.
    Check rear heater box flaps to make sure the cable isn't holding the flaps open!
    caught up any where if engine has been out several times during engine / gearbox removal

    Lowlight bays heater controls are a bit different. What has been described above are for high light bays. May have been an overlap??

    Sorry Grant....I misread your post.....I read the T3 references and assumed it was a T3 diagram.....having all those options is what threw me :rolleyes:
