K so i'm having problems with my sunroof on my si.

It was leaking through the sunroof so i looked and someone put like house seeling stuff in the drain hole above the drivers seat. so i blew that out with air but now water is leaking into my car on the floor under my clutch peddle! i have put drain fluid down it and it didn't work, and the other day my roof leaked again when it rained pretty hard.

Has anyone had these problems before? I really need to get this fixed it is recking my roof lining!!!! Thanks!!!
