At nearly 39K I'm experiencing my first "major" problem. Whenever the climate control system switches to fresh air from recirculate(either automatically or manually by pressing the switch), I hear a loud knocking(rap rap rap) noise coming from the passenger side dash. It can also be heard outside the car from the passenger side cowl area. The noise lasts about 15-20 seconds. It only does it going from recirc to fresh air. Switching back to recirc works fine with no noise. The door is still opening and closing as I can tell the airflow changes, however, when selecting fresh air; I get the noise then once it stops the fresh air door opens. I'm scheduled to take the car in next week and I have a Mopar Service Contract, but any ideas on what it is? I'm hoping it's just the actuator as anything else will likely involve tearing the whole dash apart to fix.
