Sunroof drain tubes Nissan Part 2 READ DISCRIPTION

Leaking drain tubes are discoloring the headliner in front and back corners. DO NOT use metal wire to run down the tubes it can rip the rubber. I thought I had it figured out by cleaning the tubes.. but the rear tracks connect to a plastic tray, these leak. The design is Horrible!!!! I actually had to remove the rear white trays under headliner and use silicone caulk to seal them. I am not even sure if I fixed the issue. THANKS NISSAN!!
