I have the 2002 grand prix with the 3.1. The drivers side air is super cold, but my passenger side air is warm and hardly blows. (already refilled refrigerant) So i removed the cover that leads to the cabin air filter to check and see if it needed replacing. Well, It was missing. (recently purchased the car) So being the loser that i am i tried to move the door that leads to the blower manually by pushing on it. I felt a pop and now the door moves freely. I think i just broke something. haha Now i have no idea on what to do to fix it. Any advice?
