I had access to the car for about three hours and I checked the main air dooor flap it works correctly, the recirc fresh air damper also works correctly. This was all done with glove box out. Next time I see the car (and kid that is away at school) I will definately try the defroster vent pod. Could fan rotation be backwards ? If I swap the leads will this reverse the polarity and make the fan spin a reverse direction ?
