Having had an elusive pool of water on the passenger floorboards (front and rear depending on how car is parked) of my 2010 SHO non-PP over the past years, I finally took decisive action and stripped the interior.
While the interior is out, I ran a hard stream of water to simulate the thunderstorms we had this weekend and confirmed that the sunroof's front passenger drain was my problem. While I already knew it (the drain line was clearly disconnected), it helped validate my suspicions and direct a fix.
I then used .095 trimmer line to verify the drain lines were clear of obstructions, used an air compressor to push under 10psi of air through the lines while listening for (and receiving) the whoosh of air sound at 4 corners, and did the same process for the sunroof drain holes.
When reconnecting the drain lines to the sunroof's drain holes, I used small zip ties to ensure this problem is (permanently?) fixed. Subsequent water testing showed the sunroof is not leaking and a slower stream showed the water was coming out in the 4 corners where the drain lines would terminate.
It turns out that my journey isn't done as now my HVAC fan blower is leaking, too. Already looking for a less expensive cowl as Tasca Parts has it for nearly $250 (I'm still looking) and I need to check the cowl drain plugs.
Since I've got it all apart and taking my time cleaning carpets, seats, headliner, etc., I took pictures of everything I can recall people asking about. I plan on taking a slow speed over this weekend to put it all back in. Please overlook the mess as she's been a solid road warrior for 13 years and is pushing 200K miles.
If you need additional pictures, please let me know.
Pics 1-6.
