Hello all! I am new to this site but an 8 time owner of MC's. I bought a 2004 SS a couple years ago with 32,000 original, garage kept, clean as a whistle. Last year I had a problem with water leaking into cabin after using sunroof (ASC) and I adjusted with it in the vent position using a small Torx driver to tighten sunroof, that worked fine, just a very minor procedure. This winter after taking a trip up north, I noticed the passanger side, back seat floor was soaking wet?!! Not long after I started to notice a "swishing" noise, thinking it was the gas tank? I am convinced its the roof area, behind sunroof? I gained access to drain lines in trunk behind felt matting, they are both dry and I can blow thru them. The sunroof track is dry when opened and visually inspected...any suggestions without taking sunroof out? are there any other draining systems or areas that can retain water now that sunroof was installed?

 

Welcome to the site. I was thinking maybe the drain line came off but I dont know how it really could. Maybe this pic will help a bit.

 

It dont take much for the drain hose to come off, its just pushed on the plastic, what i usually do is remove the headliner and set in the car and have someone use a water hose and run it ove the sunroof, best way to find the leak

 

Thanks LouGreen for the info...#6 on exploded view you sent seems to go down the inside along frame, down where the door jam is?? behind plastic trim on inside? I hve found 2 tubes coming out in the trunk?

 

There is 4 drain tubes 2 that run down the back that you found and 2 that run down the windshild post and come out inbetween the door hinges like this
