Heating / air driving me crazy !!!

Well I though it was only EATC, but it appears manuals have a electric actuator motor that is addressed below. Here's what the TSB addresses:
EATC—INTERMITTENT WARM AIR OUTPUT TSB 08-23-6
TEMPERATURE SET 68-72 F (18-22 C) EMTC—INABILITY TO CONTROL TEMPERATURE OUTPUT
FORD: LINCOLN: 2005-2008 F-150 2006-2008 Mark LT
ISSUE NOTE
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 ****. Some customers may also complain the heat cannot be reduced without rotating the control **** well into the
Cool/Blue range.
WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited ACTION Warranty Coverage
I never have good experience with warranty work, so I replaced mine myself. It's not a difficult job, but access is extremely tight. The part is about $25 and it's part no. 9L3Z-19E616-E Actuator - Motor Asy. Ford allows dealerships 1/2 labor for the warranty repair. Removal of the radio and glove box door are necessary for the replacement.

There is a wiring harness that runs on top of the actuator. If you pull the harness from the mounting tabs it makes it easier to access. Because access is so tight you need a small wrench as a socket won't work for all the bolts. I used a small ignition wrench, but I don't recall the size. The motor basically lifts up after the 3 bolts are removed. Just reverse to install.

I just took mine in for this problem and the dealer quoted me $700 for replacement of the HVAC actuator motor control assy! I crawled under the dash, drivers side, the part was clearly visible, on the side of the plenum just to the right of the gas pedal.
