Question 2005 Chevy Silverado 1500 HD - A/C recycle button won't work

A/C works, but when the recycle button is pressed, it lights up but does not kick into maxium air as it used to do. Any help or suggestions on what we might try to get this working properly would be wonderful!! Thanks in advance!!

I think your talking about a recirculate button, this button sends a discrete voltage signal the hvac control module with then in return acts to control a door accuator that shuts off air intake from outside and recirculates the air in your car to get maxim cooling. Listen for the door moving with the button pressed, also listen for binding or clicking which would indicate a door/ accuator problem.

Yes, this is the button we are talking about. When checked with your suggestions, there is no noise or anything. The small green light does appear when pressed, but that is all that happens. First, where is the door/accuator located? Second, is this an electrical problem? Third, any other suggestions on fixing would be wonderful!
Thank you!!
