What is your question?
My 2009 Silverado 1500 is only blowing Out of the defrost vents, no matter what the dial is selected at. I was told it was the actuator, but which one and where is it located?

possible vacuum leak under the hood,passenger side near fire wall.most of the time when that happens,the vacuum leak will cause the blower motor to default to the defrost mode only.
