thats most likely what it is. either that, or something has fallen down the defrosters and its blocking the blend door from opening or closing

That is correct, the air blend door actuator. "flapper valve" may need to be replaced or cleaned and free from binding up. Good luck and hope this helps. If there is an Auto Zone in your area, they can order the part you need and give you the step by step instructions to removing the old actuator and replacing it if it's damaged. Good luck and keep me posted, be glad to help.

Either the door that controls whether air from the heater or ac is stuck in between or the ac system is having trouble. Minivans sometimes have seperate compressors for the rear and front.

Your passenger side temperature door actuator is bad. You can access the actuator by removing the glove box & hush panel. The actuator is on the side of the HVAC box. If you can gain access to the actuator watch the center of the actuator as you change the temp on the control head, if the actuator does not move it is bad, if it does, the door inside the HVAC box is bad. Most likely its the actuator. If you remove the actuator & open it up you will most likely find the large center plastic gear is cracked all the way through. It is held in place by 2 or 3 7/32 screws. Once you replace it, disconnect your battery wait 30 seconds and reconnect it to reset the HVAC control head so it can relearn your actuator positions. It can take up to 5 minutes for the control head to go through it's relearn procedure. You can try resetting the actuator first , but make sure your radio is turned off before you disconnect the battery and if your luck, the actuator may not have any broken parts and the gears may just need to be freed up and lubed. Good luck friend and hope this helps.
