Default Climate Control problem on later model fords?

Hi All.

Anyone have any problems with their climate control in the later model fords? I keep my cab set on auto around 67 or 68 degrees. On a trip recently - the outside temp was around the same temperture. With the AC on - sometimes the truck would start blowing warm air then switch to cold and switch to warm - with the cab feeling like it was around 72 or 73...

This happens on another buddy's 2007 ford f150 and in my parent's 2007 mercury mariner.

Mine's an 08 - so if a sensor has gone bad already - i would be surprised.

Any TSB's on this or other possible solutions?

Thanks!

Edit - Found this TSB somewhere else:
08-23-6
EATC - INTERMITTENT WARM AIR OUTPUT TEMPERATURE SET 68-72 F (18-22 C)EMTC - INABILITY TO CONTROL TEMPERATURE OUTPUT
Publication Date: November 3, 2008
FORD:
2005-2008 F-150LINCOLN:
2006-2008 Mark LT

ISSUE:

Some 2005-2008 F-150 and 2006-2008 Mark LT vehicles equipped with Electronic Automatic Temperature Control (EATC) may exhibit intermittent periods of warm air output in Auto mode with the temperature control set between 68-72 degrees Fahrenheit (18-22 degrees Celsius). Some 2005-2008 F-150 vehicles equipped with Electronic Manual Temperature Control (EMTC) 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:

Refer to the following Service Procedure to correct the condition.
SERVICE PROCEDURE



The condition may be caused by a faulty temperature blend door actuator.
Check actuator activity.
EATC systems may be monitored with the IDS PID (LBLNDPOS).
EMTC 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.
NOTE:THE IGNITION KEY MUST BE OFF WHEN REPLACING THE ACTUATOR. ENERGIZING THE ACTUATOR BEFORE INSTALLATION ON THE HEATING VENTILATION AIR CONDITIONING (HVAC) CASE WILL CAUSE THE PART TO BECOME MISS POSITIONED AND CORRECT ORIENTATION WILL BE LOST. INCORRECT ACTUATOR OPERATION MAY RESULT.
