It may be out-of-sync. Try to close it all the way and see if it "clicks". You will know once you get power to them. They can be closed manually, foward and backwards, but it is not advisable to do it. From the Ford Manual page 103:
The powerfold mirrors may be folded forward/rearward manually to any
of the three positions shown and electrically to positions 1 and 2 only. If
a mirror is folded manually forward to position 3, you must manually fold
it back to position 1 or 2 in order for the powerfold function to continue
Note: Ten or more switch activations within one minute, or repeated
fold/unfolding of the mirrors while holding the switch rearward during
the full travel may cause the system to disable the fold/unfold function to
protect the motors from overheating. Should this occur, wait
approximately 31⁄2 minutes for the system to reset and function to return
Note: The powerfold mirrors are designed to operate while the vehicle is
stationary or traveling at moderate speeds. If you attempt to powerfold
the mirrors at high speeds, they may not fully fold forward/rearward -
slow down and powerfold or manually fold the mirrors in order to
complete the fold operation.
If the powerfold mirrors feel loose or fold very easily, it is possible that
the powerfold mechanism is out of sync. The powerfold mechanism gets
out of sync when a mirror is manually folded partially in toward the door,
then electrically powerfolded.
Note: The mirrors will not be out of sync if the mirrors are manually
folded all the way in or out and then powerfolded.
In order to re-sync the mirrors, manually fold the mirrors toward the
door until a click is heard. Then press the powerfold switch to
electrically fold the mirrors in then out."
