Need Help with Rear Sunroof Drains!!

I've been having a problem with water somehow getting underneath my rear seats, and under my spare tire without any sign of it; until now. I took apart the rear C pillars (the ones on either side of the rear window) and poured water into the sunroof drains... found this...



That is water pouring through one of the bolt holes on the driver side rear C pillar. I'm not sure where the water goes, but it shows up under the seat and then in the trunk.




Looks like I need to run a new sunroof drain hose down there. Anyone know of a good write up and/or diagrams to do this with? I'm guessing I will have to pull down the headliner and should have a pretty good shot at the hose from there, but where does it connect to down near the fender??? We're supposed to be getting a lot of rain in the next few days so I need some help ASAP

Any advise and/or pictures would be much appreciated!!!

Try accessing number 20, (yes , under the headliner as you suspect) it is the water outlet hose that connects to the drain line running down the C-Pillar. The line probably came off that outlet or your problem will become evident once you access this rear outlet hose and follow the tubing down the C-Pillar.
I don't think you'll need any more diagrams, to see where the hose ends up draining, as I believe you'll need to fix something within 2 feet of this outlet.
