As long as there is 12 volt DC power to the switch, the open/retract switch for the awning should work.
The blade fuse MAY NOT be in the power center. It may be BEHIND the power center on a "pigtail" fuse holder. Remove the screws holding the powercenter to the wall and slide it out. You should see one (or several) pigtail fuse holders. Pop the caps off and check the fuses. One of them should be blown.
Youcan also remove the switch from the wall and check for power there with a 12 volt light tester or multimeter. If no power, then the fuse.
If there is power at the switch, it could be the switch or a bad awning motor.
