So I think we've all heard of water in the floor, not sure if it's one side more than other. Been washing/spraying off my car a bunch this fall as it parks outside and needs a morning clean. Anyhow, just found water on carpet, pulled that and all electronics are dry. Funny we found a screwdriver in there too...not mine!
Anyhow, sunroof drain vents are perfectly clean. Car tilts to passenger side in driveway, and if you open hood and pop the plastic cover below the windshield you'll see the AC plumbing and other stuff going into the cabin, without the best seal. This is my thought on how the water got in. I'm going to seal up the area with some silicon. Just a heads up to seal this up before anything bad happens...bit too easy to get water in.
There is a ton of wiring down there too...
