306 gti water intake problem

Dear friends, hello everyone.
My vehicle was 99 306g
In these last oils, I inserted the illumination unit from the top of the sunroof with water from somewhere on the top, but I could not see where the water came from, even though I looked at it with a lantern as it took water drop by drop.
Thanks..

Black chicospastic draft for the joining of the sunroof water channel to prevent the evacuation ducts from controlling.

Hello my friend. I was interested in sunroof today.
One of the evacuation channels was blocked. I solved the problem.
Thanks to you. Thank you ..
