Replacing blend-door motor...
My 2012 FX-2 Supercab has recently began blowing only cold air out of the driver-side vents no matter what the temperature is set at.
It makes no difference if the system is set to single-zone or dual-zone...it blows cold air on the driver, warm air on the passenger.
I think I have deduced it is the blend-door motor for the driver-side of the unit.
I bought the motor today for $12.31 from my local dealer.
Some places on the 'net claim this an easy job, and it sits within easy ccess right behind the radio/ nav unit...others claim it is on the bottom of the HVAC case and at the very least the entire console has to be removed.
Anyone here have any experience with this?

Would be appreciated..it seems for many it tends to go out after the warranty is up
thanks!
Not sure which one it was considered but mine was behind the head unit i removed that and popped the glove box door down and was able to remove mine and replace it. It was located top right of the touch screen i think it was temperature door. Look on youtube i know theres a few videos
It's a very long procedure... If I can find a easy way to post it I will if not I can send it to people who need it
Do the new actuators need to be "calibrated" or aligned in any particular way either before or after installation? Should the temp control be on full-cold or full-hot before installation, or any other pre-setting method?
Or does it make no difference?

no difference they are key way so it only goes in one way some times you need to put the post in then turn it so the screw holes line up
Well, I did it!
Took me about 4 hours. Took the seats and console out and rolled back the carpet.
Removed a bunch of brackets.
Took as many screws out of the lower blower case as I could reach: (6 of them)
Used a big pry bar to hold the case halves apart enough to wedge a tiny 8 mm wrench in there and removed the motor/ actuataor screws(2). The motor is in front of the console on the bottom of the blower case, sandwiched in between the blower case and the lower heat duct. It is slightly to the right of center.
Getting the motor out was a combination of wiggling, prying, cursing, screaming at it, taking a break and then talking gently to it. It finally came out.
The motor and shaft are keyed, and of course the old motor did not fail in the same position as the new motor is keyed out of the package.
So...I took the old motor apart and used the removed drive gear as a tool to stick up inside the hole and use as an alignment tool to set the blend door gear in the proper place to accept the new motor correctly. I simlpy put a black mark on the keyed part of the old gear with a Sharpie so I could see where it was lined up. There is no possible was to actually see the teeth of the geared shaft of the blend door while it is all still installed in the dash.
Of course there is literally NO EXTRA slack on the wiring harness to manipulate the pigtail back into the new motor,
So...I made a long loop of a skinny zip-tie around the back of the pigtail, lined up the pigtail in the new motor's socket and pulled the zip to seat the pigtail. Worked like a charm. Simply cut the zip off afterwards.
Worked the motor back in place, and with the gear shaft lined up properly, it went right in.
Put the carpet and trim back, all the brackets, console, shifter and seats back in and fired her up.
Works like a champ!
Saved a bunch of stupid money, but sure hope I don't have to do that again soon.
