also check to see if tube that runs your climate door is not pinched or broken. the vaccum tube that runs the climate door is behind and under the battery. i had same problem a year ago and the tube was partially cut. i fixed it by cuttinga piece of aquarium tubing and spliced it back together. one other thing.....check to see if your radiator over flow cap is tight. your cap maybe bad and or cracked this would also cause the problem.

Problem with the blend door actuator or wiring going to it (no separate fuse). Most of the time the actuator motor fails and won't close the blend door. I can't guarantee that it isn't a broken wire going to the actuator. It should set a trouble code in the BCM (body control computer) if its electrical because it looks for a feedback as to where the door is positioned.
