Yes there is both a door and a flapper you have a problem with a blend door motor, it is not switching to cold it is half open and half closed so you need to replace the motor vacuum motor it is under the dash near the heater on the passenger side and if it is the other motor under dash you will have to take part of the dash apart to get to it, to test buy a piece of vacuum hose 1/8 inch diameter about 3 feet long and you can hook it to each of the vacuum motors and **** on the end of the line to see which one is causing you the problem, also could be the control head for the AC inside the car where the controls are, you have to remove the ac cluster ot get to the vacuum switch it's all vacuum operated and if you pull it out you will be able to here an audible sound of air leaking if it's the switch.

Need to check to see if the blower motor is running.If it is,but not threw the vents,most likely a vent door actuator motor.The actuator motor in this case would be bad,it is hard to get to,unless you are mechanically inclined,You can do it your self.If the blower motor is bad,just replace it.Check fuses first,and the blower relay.If I can help,let me know.

It sounds like a heater blend door issue inside the heater box that is actually not closing all the way to allow either cool or hot air or visa/versa.

Same problem. I have a 2005 on a Rockwood Roo. Worked fine in October 2009. Not working June 2010. Problem is not a freon leak, compressor went bad. I banged the compressor gently with rubber mallet then with a hammer but that did not work. The fan runs, the compressor runs but gets hot. Also no indication of freon moving through system as everything gets warm from the compressor outward.
