2002 Sportsman 700 12v Aux Outlet

The 12v auxiliary outlet on the left side of my headlight doesn’t work. I attempted to reference the wiring diagram and that didn’t help me out much at all. I was wondering if these are known to just quit working over the years due to the elements or if there is possibly a fuse or some other simple solution that may have caused it to quit working. Any help that can be offered is appreciated. Thanks!
