Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.
You will want to see if you can tell if the blend door actuator is moving, and that the rod did not pop out. The procedure to replace it requires the dash to come out though, but you may be able to see up in there.
The blend door actuators are reversible, 12-volt direct current (DC), servo motors. Models with the single zone heating-A/C system have a single blend-air door, which is controlled by a single blend door actuator. Models with the dual zone system have two blend-air doors, which are controlled by two blend door actuators.The blend door actuator (1) for the single zone heating-A/C system is located near the center of the HVAC housing (2), close to the dash panel.For the dual zone heating-A/C system, the same blend door actuator used for the single zone system becomes the driver side blend door actuator, which is mechanically connected to only the driver side blend-air door. A second separate blend door actuator (3) located on the top of the HVAC housing is mechanically connected to the passenger side blend-air door.
I have the instructions in a PDF format that you can download at the following link. Please don't forget to come back and hit the accept button though, that is the only way we get paid, thanks
