After removing all the interior trim, I was able to squeeze my arm in there. It was tight though and it wasn’t easy, but I’m just glad I found the leak.
Holly smokes!!!, I don't have a a sun nor a moon roof, but maybe my drains are completely disconnected because my drives side.. water gets on the floor carpet, i have a 2003 Coupe ugh i just had the windshield replaces. I hope that fixes the issue. And if it does not... then I will have to check that.. what you just checked for. Thanks man Great vid!
I saw another video about this problem. What happens is over time that drain tube shrinks, and disconnects itself from the lower drain tube. Here's the link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nuVn-VVdm34.html
