Sunroof drain leak

[Pillarian]

Hey forum:

Thought I would pass on my experience with this problem. I haven't done a thread search, so others may have had this problem.

I had a water problem that soaked into the sound insulation under the right rear back seat and into the floorboard pan for that seat. Tracing the leak up resulted in the conclusion that the leak was in the door seal or roof somewhere. 3M makes this black weatherstripping glue that works very well. It comes in a red tube. The door seal wasn't the issue. I gently pulled back the headliner. The sunroof pan has a drain spigot with a drain tube that is not secured by anything not even a hoseclamp. The drain hose pulled back and off the spigot causing water to run down the inside panels and to settle under the back seat. Its a leak that is not apparent but looks likely to recur in other SHO's. Problem is solved. I had to lose the sound insulation (moldy) and clean with much disinfectant, but the smell is remedied. Now I've got to track down the one-way panel fasteners that all broke, of course. Noise levels are uneffected. I have a 94, ATX, green, 130K, no rust (yet).

FWIW.

with your experience from pulling the headliner...would you be able to tell me if it is possible that one of the rear lines being off could be the cause of the rear section of my headliner to be falling, and a calcium deposited spot around one of the plugs that hold the headliner up in the rear?

I had a slight build up of minerals from the dried water in the headliner. I don't know what prolonged water exposure would do. Its possible that moisture exposure could turn the headliner to mush. The retaining buttons break away with relatively little force, but be careful. The headliner is fragile.

oh i know the headliner is fragile! besides that i have recovered a few before on my other cars. this one i havent decided if i want to do it. but i tried to patch it back up...its sagging in the rear most parts now, and that mineral deposit back there, but when i lightly touched the fabric, it feel off into my hands, so i never beothered to try to venture further.

although i do know that all my drain holws are clear...nice sunny day with the moonroof open dribbling water around the track, water came down before each bumper. oh and my headliner doesnt actually ever get wet.
