Check out the diagrams (Below). Please let us know what happens.

Recirculating air switch not working. Outside air, odors and dust are coming inside the cab when the a/c is on and the recirculating air button is turned on. I looked under the dash board and I see that when I change the air vent positions everything works but when I press the recirc button nothing happens. When its cold, if I have the windows up, the a/c off and the recirc air button pressed, outside air and dust still blows through the vents inside the cab. Anyone has the same problem? How can I fix this? Help please.

I found the problem. Found the actuator for the recirculating air flap door and I wiggled around the wires. It started working. Maybe it was the connections or something. I'm sure that the actuator is starting to go bad so I will keep checking until I have to replace it. However, it look like a pain in the ass to do.

Good job yes agree actuator going bad and yes real pain to do.

I am having the same problem on my 03. Where did you locate the actuator?
