the motor for the blend door might have gone out. its pretty simple to check the motor. all you have to do is turn the car on, engine off. wait for all the beeping to stop and then turn the temperature from cold all the way to hot, or vise versa. if you listen carefully you should be able to hear the motor working under the dash. if not then you have your answer.
i dont know how hard it would be to switch it over from the automatic to the manual.
