sunroof drains water into the car
the sunroof has drain tubes, they are clogged with debris. you need to either blow them out with an air compressor or very carefully put a wire down to clear the blockage. you do not want to Poke a hole or tear the drain tube.
Spell check strikes again 
opps, sorry. LOL
well, I am glad it did not say Polka a tube. they would have been dancing on the roof. LOL
May I please hear the Beer Barrel Polka? Thanks.

Although I’ve never done this myself, I’ve heard multiple times that string trimmer line is ideal for doing this.
