Water in passenger quarter panel

I just purchased 2013 Mustang convertible, after driving it for the day I noticed water dripping from the passenger rear passenger quarter panel. With the top down, I used a flashlight to look down into rear panel. I noticed water was pooling there. Is there a plug on bottom rocker to release the water. I noticed this seems to happen on other years also. Any help would be appreciated.

There is a weep hole.
It's just big enough to put a small screwdriver in, to clean it.
Near the pinch weld behind the tire, it is not easy to find.
Most likely, it's just a bit of debris blocking it.
