Water leak/Sunroof drain repair

Hi guys. So last year I had a leak in the front passenger side caused by the sunroof drain becoming disconnected. That was an easy repair (and posted on this site).

Now, I fear a rear drain tube is loose. I had no problems until I came home from being gone for 3 weeks. The middle of the rear floorboard is wet. Just that part directly behind the console. Every time it rains, that area gets damp. I figure/hope itís a sunroof drain issue like before but I donít know for sure. Has anyone encountered this?

Appreciate any guidance. And yes - Iíve searched the board.

Now I own a 2012 and my sunroof drains ( one on each front corner ) both drain to the front, right next to the inside of the front tires. When I check and test my sunroof drains I never see dripping from a rear drain. Is it possible the sunroof frame itself has lost its seal but on the back side and now it is leaking on the floorboard in front of the second row seats ?
