I'm posting this problem on behalf of my father.He has an '03 Sierra that has a squeaking type noise coming from behind the center of the dash.When the mode switch is moved,the noise changes or sometimes stops.Now the noise has stopped and airflow is only coming from the upper vents,regardless of where the selector is set.Any help would be great! Thanks!!

Could you tell me where the actuator is located and what is involved accessing it? Thanks again.
