No air will come out of any vent om my Contour. Nothing from defrost, vents or on the floor. I can hear the fan blowing air and when I removed the glove compartment and manually moved the arm I was able to get air to the defroster. But as soon as I let go of the arm, it returns to the closed position.
I've removed the center panel and looked behind the selector. When I removed the vacuum hose connected to the back of the connector I feel no air or vacuum, even if I put my thumb on it and cover all ports.
