When we were purchasing our camper, the fella at the shop noticed that the awning LED light strip wouldn't come on with the switch. He said he couldn't figure it out so he just unplugged the strip and put another LED strip over the old one, and wal-laa, it works. So, none knows why the original stopped working, but the light switch was fine.
These units can be wired so weirdly, it's possible there is an outlet associated with the awning light.
