Both really. The bottom line is, I can't stop the flow of air coming through those dash vents. In the summer it's fine, but got awfully cold back during the winter. I turned the round bezels to try to block the air, with limited success. The cables may be disconnected from the flapper valve, but even if I fix that I still have one bad cable (drivers side) and one broken dash mount bracket (passengers side).
Will start putting the interior back together in 2-3 weeks.
