I managed to remove the two air blend motors, but now struggle to re-install one of them.
The motor I have sits in a position that does not align with the key on the shaft of the blend door. I am therefore not able to install the motor, unless I find a way to either rotate the motor's shaft of the flap door and to keep it in in this position until I have the motor installed.

I'd appreciate any ideas!

 

Possible to plug in and actuate via the controls on the dash while its not mounted?

 

One makes the assumption that it is a identical replacement

 

I know this old but I have this problem as well
did you fix it?
