I finally pulled the headliner to replace it & find the sunroof leak. I fully expected a clogged drain line. This was in the truck when I bought it so I have no idea who put it in or when.

SURPRISE! No drain line.

Now I get to put up a fresh headliner & get it all ruined because the sunroof will keep leaking around the glass.

I was thinking about putting some self-adhesive heavy huty weatherstripping either on the bottom of the glass sunroof or atop the rubber (or whatever) seal that is already there that the glass closes onto.

Anyone have a better solution or a real fix for this Webasto stinker?
