I suspect I’m having problems with the rear drain tube for the sunroof. Ive got water coming out of the second row vents, condensation on the inside of the windows etc. I’ve read all the posts and know how to go about fixing the issue if it’s the rear drain tube. However, I’m not sure how to locate the tube to check it. Do I need to drop the head liner? Where does the tube end and drain the water? None of the posts I’ve read discuss the rear tube in detail. Thank you!
