Here is an option for checking for power at the motor and if the motor works. Hopefully it applies to your awning.
With the aid of a tall step ladder, you can reach the motor power connection on the top of the right awning arm. Unplugging this will allow you to apply 12vdc and ground directly to the motor to see how the motor responds to power directly from another source. On a neighbors class a, we found that his issue was not the motor, but a power connection that was corroded. Reversing order of the two wires reverses in and out.mine has worked flawlessly for almost five years of fulltiming so far...knock on fiberglass.
