I have cold air in passenger vents and warm air in drivers vents. I have removed the drivers side vent door actuator and can turn the shaft on the door by hand. all the way in one direction I get really hot air, all the way in the opposite direction I still get warm air instead of Cold AC Air.
What can I try next. The door does operate when I turn the shaft because I can hear it botom out in both directions. Replacing the actuator won't fix this problem because it still does the same thing with it out of the circuit. Any Ideas on what to do next?

Nice diagnostic procedure, it's good to see someone actually try to determine what the problem is instead of replacing parts, which is way too common.
I see you posted this awhile ago, so where you able to find out what the problem was? Was there another door inside the dash that wasn't operating properly?
