Car has sat since Friday. Rained Saturday and Saturday night. Passenger floor is wet but area above is pretty dry. I can’t seem to find where the water is coming in.
Could be from your windshield area seal gasket
I fixed mine with aerosol flex seal, so far it's holding up
Cowl drains can be plugged up, if the drains are clear from experience heater box seals do become brittle and crack. Under heavy rain conditions leaks like you described can occur as did on my 300. Your 2nd pic shows rust stains to support this. DMT sells a complete reseal kit that works very well. Keep me posted on your results.
mine is doing the same thing...im finding it to be the weather stripping around the door near the top of the vent window...water is leaking in there and following the edge down to the floor...maybe check that.we have had continuous rain all day. Pulled the carpet back and it’s dry. Seems to be coming in the side. The floor closest to the scuff plates was the wettest.
