Pretend you popped the hood, and you are looking at the passenger side area under the windshield. The trim that runs under the wipers has been removed.
What you are seeing is the end of a drainage tube that runs from the front corner of the sunroof, down the A pillar to here. There is a hole in the frame where the water exits through the wheel well to the ground. There is also one on the driver side too, but I couldn’t get a good picture because it is under the wiper motor.
There is a disc in the center that is designed to make a stream of water “spray” instead of being a steady stream. It is so close to the flow that it gets clogged with debris. I discovered this by having my sunroof “leak” down the A pillar on the inside of the vehicle because it could no longer drain down the tube.
According to YouTube University, the solution is to break off the center disc, and once I did that some backlog of water immediately flowed out. I was warned not to remove the entire fitting as that could cause the tubing to pull off the nipple and hang loose in the firewall.
Now you get to learn from my failure! If you have a sunroof, you might want to investigate whether it has drain holes, and if so flush them occasionally.
