Hey all,
Recently my truck, a 2000 silverado extended cab, has developed a knocking from inside the dash on the passenger side. I took the lower portion of the dash apart and discovered that it was the recirculation door for the a/c system. While the truck is running, with the HVAC controls off,
the door will try to close about a dozen times creating the knocking sound. Is this as simple as replacing the recirculation door motor or am I on
the wrong track?
