After replacing the blend door, the A/C controls do not turn off the front vents?

Since I replaced the driver side blend door my A/C controls will not switch off the front vents. There is also nothing coming out of the rear vents. Any suggestions?

It sounds like the orientation of the blend door drive is not timed correctly or the actuator is defective. Also, it says to Initiate the Actuator Calibration function using a scan tool, did you do this? Check out the images (below). Please let us know what happens.
