HVAC temperature issue
I searched "blend" and went through several pages of results that didn't answer my question. So now I ask you guys about these blend doors.
Yesterday, the temperature of my cold AC changed to warmish. I can still change the air output between floor, vents, and defrost. However, mine isn't cold anymore. I assume a blend door failed.
I did check the AC lines to the compressor to make sure they still had good pressure.
So, assuming it is a blend door actuator...which blend door actuator failed? I'm hoping it is the one where they don't have to pull out the whole dashboard. If you think it's something else, let me know.

From what I read on the net, pull the fuse for the climate control, start the truck, let it run a couple of minutes, turn off and replace the fuse.
Restart and let it run at least 3 minutes.
May or may not work.
On the Edge.
You start the Edge with the climate system off. Press and hold the power on button for 3 sec. while holding the power button, touch defrost, release both and touch power twice and it will immediately go into a reset.
I have read that may be a universal reset for all Ford's....but I have not tried it.

Try the power reset first as explained here.

If you have Sync I would try to reset it also.... before I pulled the dash.
The F250's have a TSB for the blend door.
