I am having some trouble with a leak coming from the front passenger side.
The water is coming from the side panel at knee level. Next to the heater fan.
I used a small camera to find the source and it is coming from the windshield bottom right corner area/ top side of hood hinge pocket. The windshield seal looks pretty good so I don't know.... Here is a video of what I found. The quality is far from perfect, but I was thinking that someone might recognize the leak pattern. You'll see in the video a small white plastic tab near the source, would be great if someone could tell me what is this tab for so that I could pinpoint the leak a bit better.
