if you have a sunroof its the right sunroof drain....i had that same thing a while ago...
before you disagree heres the story...
the sunroof drain leaks into the headliner edges runs down the plastic panel and into the door jam as shown in your pics.
it got my fuse box wet and blew the fuses..... just try and see by pooring water into the drain to see if it comes out if not theres your problem
