Harsh, but OK. I have offered thoughts a number of times, and no one seems to pay attention (for the same reason, I believe). Of course, I could be wrong. Maybe my thoughts are just useless.
No, I don't know anything about the drain lines. I think I asked (in my first post) if anyone knew what to do to see if they were plugged and had any ideas how to clean them. Crickets ...
As an FYI, I always search out a solution well before posting. If you look around, I have made very few posts looking for answers (a handout, as you say). The search function here is awful, and I have mentioned that before. Not saying it's an easy thing to fix, but it's bad - not usually helpful.
So, when I post, I need help, and I'm not looking for a handout. I've read posts from people tearing these cars apart from top to bottom. When I ask about a sunroof, it seems like someone would have had the type of issues I'm having and are just choosing not to answer because of the "social-club" mentality. Unfair criticism? Maybe so, but it's an honest observation, and I have been around here a while. With over 200 posts and years of time, it's not like I don't know something about what I'm saying. Ignore (or criticize) my comments if you must. It's your choice, but things won't get better if you do.
If I figure out my problem, I promise I will post back with the solution (as I have previously).
