I offered a WAG on your other post but if you here or see nothing then there's something wrong with power or motor. We've had to have some wiring done where it was supposed to be but was not.
Have you tried checking the DC fuse panel...should be a 10 or 15A fuse for the awning. Replace the fuse regardless if the little red LED is on or off as they don't always work to indicate a blown fuse.
