Water on driver's side floorboard

[BUNNY15]

So for a while now I have experienced the dreaded water on the driver's side floorboard, but recently purchased some new roof marker light gaskets hoping that would solve my issue. They were nice and thick compared to the shriveled, weathered factory gaskets. I scraped off as much of the old gasket and applied the new gasket that was a simple peel and stick application, and installed them last night. Tomorrow there is 100% chance of rain in the forecast, so I'll know for sure soon if that was my problem.

Yep, roof marker light seals (I sealed mine with clear silicone caulk) and a clogged sunroof drain are the top reasons for water on the floorboard

I had to reseal the front windshield as well, but it was real clear it was leaking.
