The motor that operates the shade also operates the wind deflector. I can only assume there is some sort of "feedback" (for lack of a better word) when motor operates the wind deflector.

The "wind deflector" is not powered by anything. Simply spring/tension loaded and rises as the window frame slides back on the track. Same with lowering - the glass pushes down on the support arms as it slides forward, lowering the wind deflector.
