1997 Chevrolet Silverado K1500 4x4, 5.7 Liter V-8
The control **** which selects if air blows out the defrost, front, foot, or etc vents operates perfectly and the blower motor does also. When moving the control **** from foot to defrost (as one example) you hear a air whistling sound and then I hear a door flap open abruptly then the air blows out the correct vent.
What is the mechanism called that controls which vent the air flows to?
Is this is likely what I need to replace?
