I discovered that my passenger side sunroof drain line is clogged at the outlet side or possibly disconnected at the firewall as there was water found on my passenger floorboard. It was only discovered when a bad smell became overwhelming over the course of about 2 Weeks. I have already checked the AC drain and it is working perfectly and not clogged.
To test for the sunroof leak, I slowly poured warm/soapy water in the front sunroof drains. I found the driver side was stopped up, so I used someone else's idea of sticking string trimmer line down the tube and I was able to clear it. I was not able to clear the issue on the passenger side, but the warm/soapy water was leaking in to the interior floorboard, so the tube drains, just not outside of the vehicle
I am seeking guidance on where to look for either the drain outlet or interior firewall nipple. Is the outlet under the hood? Is it behind the wheel well? Is the firewall nipple behind the dash? If so, does the entire dash have to be removed to see if it has become disconnected or damaged?
Additionally, when I was under the car checking the AC drain line, I pulled the drain outlet grommet/retainer and the water from the floorboard came gushing out. I am leaving that out for a few days in hopes that it drains any remaining water I am not happy that the passenger side floor feels slightly soft when I push up from below now.
I have searched for hours and watched many YouTube videos, but it seems that everything is about the 2nd Gen models and I'm not sure if the 2nd Gen outlet locations apply to the 1st Gen Rogue. Additionally, the videos don't show anything about locating the interior firewall nipple.
I really appreciate any advice or guidance. Thank you
