Leaky Sunroof / Wet Headliner

[stoney_]

First off, Hola mi amigos. I recently bought a 1992 Lexus LS 400 for cheap, did some maintenance and it runs decent enough now. 

But here's the new problem... When it rains for a long period of time, my headliner gets soaked. It starts on the right side near the sun roof and progresses to soak the entire headliner. Thus fogging my windows up on the inside and slightly *BLEEP*es me off. I really need to fix this problem before I move onto anything else. 

So far I've only cleaned out the drains in the sun roof and it still happens. But could it be a bad seal? Any help would be sweet or if I could get referenced to a solved topic. I really dont want to rip my headliner off but as a last resort I just might to find the problem.

Did you clean out the drains in back of the sunroof? A bad seal is easy to diagnose. Just pour water over the sunroof and seal if it leaks.
