After plenty of reading i did excatly what Weasel suggested... Pull the headliner down... Becareful but you can use some force... Make sure you don't bend it as it will crease... but go to your nearest shell and pump air down the hose and you'll see all the junk come out... I also got some club soda and poured it down as well... good as new now. Now to even go further and prevent and overflows in the future.. i used silicon to secure the track areas where water might run off to as well as around the whole sunroof frame. siliconed some of the corners of the seals as they were comming off... So far it's been great.. now to get rid of all the water in the front passenger floors...there's a huge pool of water underneath!!!
