On my Dometic awning there is a switch on the control box that shuts the wind function to OFF. Do you have that switch and is it off?
Also inside that box there is a set of DIP switches that can be changed to set what wind speed you want it to activate. Here is a chart to show the position of the DIP switch to get the speed you are looking for. D = switch should be Down. U= switch should Be UP. use a ball point pen or a paper clip to set the DIP switch

On edit, the formatting for switch positions is not working for me.
the first column is 1, second column is 2 and so on.
If you don't know what a DIP switch looks like I will google one for you.
