08 Yaris water leak troubleshooting help requested

[2bz]

My kid's '08 Yaris hatchback leaks from under the dash, between the steering column and the fuse panel. The carpet behind the pedals is wet and I think the source of the leak is in that area. There was an inch of water in the driver seat floor pan. There what I have done so far:

1. Regasketed the tail lights. They were leaking too.
2. Removed the squirrel nest from under the wiper motor and opened the drains.
3. Pulled the seats and carpets.
4. Checked the floor pan drain plugs.
5. Put a halogen lamp under the dash to see if any light was visible from the engine compartment. Light coming from AC line set opening. Not where the water is coming from but I sealed it up to keep the squirrel out. (Found a bunch of seeds and nuts under the carpet.)
6. Read all the other leak threads.

I'm kind of at a loss for where to search next for the source of the leak. Any thoughts?

Update: I just found two decayed foam gaskets behind the strut towers. Looks like the water runs off the windshield and partly down the cowl drain and partly past these gaskets. Maybe into the cabin? Applied some RTV and we'll see.


Thanks.
