There is a large movable panel that is moved by a vacuum actuator that selects the air source. Its movement selects either outside air or inside air (recirculate). The panel is covered by some type of foam insulation that degrades over time and becomes sticky. It is really bad if the driver is a smoker. This panel sticks in the closed position until there is enough force from the actuator to move it and then it makes the noise you hear. It is located behind the glove box and can be easily accessed by removing the glove box. A little cleaning in the right places will solve your problem.
