After a brief hiatus from leaking issues, I'm at it again...
Today, however, I was able to see the direction the leak is coming from- I'm seeing water dripping from behind the driver's side dashboard, and puddling into the trim around the fuse box cover and hood release lever. When I stick my hand under the dash, I can feel water dripping from... somewhere.
The plan for tonight is to pull the dash trim apart and look for the source of the leak. I've tested all of the drains and haven't found any clogging issues. The door gasket is in good shape and seems to be solidly in place.
I did notice that it was dripping rather steadily with the car parked, but I didn't collect a single drop in my makeshift rain bucket on my approx. 45 minute drive home.
If anybody has experienced similar, or has any tips on potential leak sources, anything would be appreciated.
