2000 Trooper leaks

I have water in the floor pan, drivers and pass sides front.
Can't figure out where/how it's getting in.
Windshield seal appears OK.

Any seen this?

Maybe a rusted out floor??
how big is the water spots??
are you sure its water and not coolant(a cracked heater core)?

Thats my guess based on the info provided.

It's rain water infiltrating, but I can't find where.
Windshield is sealed, can't recreate with a garden hose.
