As other posters have said the end cap on the awning has probably been rounded out by the motor shaft. This would account for a partial wind but not enough to close the awning. If your awning is still under warranty, Carefree has a new square shaft motor assembly which should last longer than the present one. If the end cap is rounded out and you have a ladder to access the awning, the end cap at the non motor end is the same as the motor driven end. The caps can be swapped and it will get you home. I would not drive the motor home unless you change the cap or secure the awning to the motor home.
