SUNROOF PROBLEMS

[K9sH3]

It is factory, and the two time before that I went in, I was told it was glog and the tubes are to small. I think that is a BS answer.
How are the tubes getting glog?
My bigger question is how the heck is the water getting in there to start with if the sunroof is closed?
I just poured a cup of water in there to see what would happen, the holes were not draining. So I went over to Amoco and used there air and blew it out. Came back home poured water again and now one side is draining outside and one on the passenger floor.
Ayne other ideas, I will take them all.
Thanks
