Locate the blend door actuator. The actuator is located behind the dashboard, usually on the passenger side. It is a small, rectangular motor with a wiring harness and a linkage arm.
Disconnect the battery. Before beginning any work on the electrical system, disconnect the battery to avoid any electrical shorts or other accidents.
Remove the dashboard panel. In order to access the blend door actuator, the dashboard panel may need to be removed. Consult the vehicle's repair manual for specific instructions on how to remove the panel.
Remove the old blend door actuator. Disconnect the wiring harness and the linkage arm from the old blend door actuator. Remove any mounting screws or bolts that secure the actuator to the dashboard.
Install the new blend door actuator. Install the new blend door actuator in the same location as the old actuator. Secure the actuator with any mounting screws or bolts. Connect the wiring harness and the linkage arm to the new actuator.

The most likely problem is either the blend door actuator or a broken blend door itself.
Both are only accessible by complete removal of the instrument panel(dash).
The blend door actuator can be tested with a Chrysler factory scan tool hooked up to the DLC(data link connector). If blend door actuator is working when tested with the factory scan tool, then blend door itself is at fault.
The only other way to test the blend door actuator is to test for 12v at connector, but you would have to remove the instrument panel in order to gain access to the actuator
I'm having the same problem except on mine it's the driver's side that's blowing cold. Do you have the pictures in a finer resolution? I can't make them out and when I zoom, they are too grainy. Does the replacement require removing the dashboard? What's the general cost of the acuators? Are they readily available at like NAPA or other parts stores?
no it doesnt ... check out heatertreaters.net if you have to replace the blend doors .... but the actuator is directly behind the glove box...remove the glove box take out 3 screws and remove actuator and replace.....waa laa

Disconnect and isolate the negative battery cable.
Remove the glove box from the instrument panel.
Remove the three screws that secure the blend door actuator to the passenger side of the HVAC air distribution housing .
Remove the blend door actuator from the air distribution housing and disconnect the HVAC wire harness connector from the actuator.
Remove the blend door actuator from the vehicle
to instal
Position the blend door actuator into the vehicle.
Install the blend door actuator onto the passenger side of the HVAC air distribution housing . If necessary, rotate the actuator slightly to align the splines on the actuator output shaft with those on the blend door cam .
Install the screws that secure the blend door actuator to the passenger side of the air distribution housing . Tighten the screws to 17 inch lbs. (2 Nm).
