LARGE TEMPERATURE DIFFERENCES - BUILD

2008-2009 F-Super Duty
ISSUE
Some 2008-2009 F-Super Duty vehicles with a build date before 1 1/06/08, 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. Refer to Workshop Manual, Section 412-01, for removal and installation details.
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.
