Sunroof drain termination?

[jeffd]

Hey-so Ive got an impressive body f water on the floorboards of my Hummer.

I've looked through a ton of threads and hundreds of photos, and I just can't figure out where the sunroof drain tubes end on my 2003 H2. If determined that they are most definitely plugged, but compressed air isn't blowing the blockage through. I'd like to try it from the other (lower) end, but I CAN'T FIND THE LOWER END!!!

Any direction is greatly appreciated. Thanks-Jeff

And actually, just the passenger side. Driver side was okay.

Well-got it going myself. Ended up cutting the hose halfway up the A-pillar and using a piece of stainless cable to break up the blockage. Alternated between pressure and suction and finally got it to budge. Blasted it all out, spliced the hose, and no more leak.
