Yesterday I replaced the blend door motor on my 09 Ranger. With the old motor out and the fan off,, and with my skinny fingers I was able to turn the blend door by turning the very top of the door mechanism. I could feel it turn and felt/heard it reach both ends of its sweep. I took the new motor from Napa and inserted the shaft just a little bit but did not screw it down. I then plugged in the new motor and turned the cold-to-hot selector knob. Once I had that knob turned to about 2oclock the door hit the far end. If I turned the heat selector knob further the not screwed down blend door motor turned into and hit the side of the ventilation housing to the left of the motor. I then screwed down the motor and tested it again with the key on but the radio and fan turned all the way down. I could hear the blend door motor groan and slow down once I turned the selector past 2oclock. The blend door motor wants to turn more than the blend door will. I don't think there is anything blocking the blend door. The blend door moved by hand easily. I could "not" feel it tilting like if the bottom of the hinge of the door was broken. Either I got the wrong motor or there is a design problem. I have read on another forum that a lot of the newer Fords have had trouble with the blend door motor failing.
