Blend door is not working. Could be the door is stuck, wiring issue, bad actuator or control panel issue. In your car, the actuator is not too hard to access. Follow the instructions to access the actuator. Check the connection. Before removing the actuator, turn the key on and change the temp setting. If you hear clicking from the actuator, it has probably stripped its gears. If not, remove the actuator and check to see if you can rotate the door by hand. If not, you will need to remove the duct to see why the door is jammed. If the door rotates by hand, plug the connector back into the actuator, turn the key on again, and change the temp setting while watching the gear on the actuator to verify operation. If the actuator doesn't turn the gear, the problem is with the actuator or the controller. Remove the connector again and probe the connector with a voltmeter. Turn the key on again and probe the terminal of the light blue wire. There should be voltage there when you change the temp setting. If not, the problem is with the control panel. If there is voltage of a few volts or more, the problem is the actuator.
