FYI: Moon roof.
Metal panel = sun roof, glass panel = moon roof.
From member MATTCHANEY: The drain tubes are on all four corners of the moonroof and are more readily seen and accessible with the headliner down. There should be a small black plastic nipple coming off the moonroof on each corner that the tube attaches onto and then routes down inside the a-pillar on the front two. mine tubes were separated from the nipple by only a centimeter or so therefore I could easily see them however if someone has removed yours for some reason or if they have crept down the a pillar some then maybe they would be hard to see. I suspect that once you get the headliner down, you will be able to see these things and visualize where the leak is coming from. before you reconnect the tubes consider putting a small clamp on the tubes to help keep them from coming off again. hope this helps.
