Sometimes the vac pod is good and works, BUT the connection between the pod and the center vent flap is disconnected (like mine was). With the pass side kick panel removed you can reach up and feel if the pod is working or not.

Bio...did I understand you right? You replaced the cener pod WITHOUT removing the dash? If so, I stand in awe! Neat trick. I could not even get the flap reconnected to the connection link....I could "feel" what needed to be done, just could not getterdone.
