Guys I'm getting barked at by the wife about no heat on the passenger side of the truck. I pulled the blend door motor for that side and it's working "well its turning" . But there is no heat for the defrost, pass. side air vent or floor heat. But it all works on the drivers side. I can not fine any info on this. Help please.

LARGE TEMPERATURE DIFFERENCES - BUILD BEFORE 11/6/2008
FORD:
2008-2009 F-Super Duty
ISSUE:
Some 2008-2009 F-Super Duty vehicles with a build date before 11/06/08, and equipped with DATC (Dual Automatic Temperature Control) may exhibit a side-to-side temperature difference greater than 15 degrees Fahrenheit (8.3 degrees Celsius). A temperature difference of less than 15 degrees Fahrenheit (8.3 degrees Celsius) would be considered normal and no repair attempt should be made. Also, it is not necessary to replace the EATC control head or the HVAC.
If equipped with manual climate control, vehicles may exhibit periods where the cabin temperature cannot be maintained with the control knob. Some customers may also complain the heat cannot be reduced without rotating the control knob well into the Cool/Blue range.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
Check Actuator Activity:
DATC systems may be monitored with the IDS PID ($9910 and $9911 ). Manual A/C systems may be observed through the right side of the instrument panel with the glove compartment door positioned downward.
Erratic PID activity or an actuator that appears to be erratically hunting for correct position during the condition should be replaced.
The ignition key must be off when replacing the actuator, energizing the actuator before installation on the HVAC case will cause the part to become mis-positioned and correct orientation will be lost. Incorrect actuator operation may result.

Here is a TSB I found, sounds like you already checked the part they want you to replace though. Maybe the motor is too weak to move the blend door under pressure?
