I have a F-150 King Ranch with an Automatic ac/heater in the summer set at 70 degrees it gets so cold that it kicks off and the heater kicks on. This goes on continuesly. The ford dealer says its a know problem and the engineers are working on this problem. They should have a fix in mid Nov. I still haven't heard from FMC . Am I the only one having problems with this?
I bought my truck in Oct. still under warranty.

 

You are not the only person having issues with the auto climate control. I have one and a good friend of mine is having issues with it. The TSB does not cover either of his nor mine they have NO IDEA what causes either truck to blow out 100+ degree air when set at 65 or higher and at 60 you better ahve your long underwear on. My 2008 has been in for service to fix this twice the next time it comes home not working the "Lemon Law" will come in to play. Good Luck

Ford has released their fix for this problem.
The latest "fix" put out from Ford is a revised blend door motor, for the issue where the A/C quits blowing cold and switches to warm on its own, then back to cold.
TSB 08-23-6. 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. The condition may be caused by a faulty temperature blend door actuator. 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
For those that are out of warranty and have this problem, the part is around $35 from the dealer. I have not done this TSB yet to find out if it actually works, but I'll be putting one on my Dad's truck soon so I'll let yall know if it works.

 

The fix for the TSB fix is a good thing. However, the two trucks I referenced the temperatures issues happen in auto and manual modes. The best part about this is Ford is clueless about how or what to fix, but I bet the corporate jets have climate controls that work.

 

LMAO, you're probably right!
