What to check next
Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Have the actual water-entry path located and the soaked interior dried and inspected. Confirm any drain-plug location and access procedure for the vehicle before removing interior parts.

Discussion summary
flooded floor
A 1986 Civic had substantial standing water in the front floor area despite repeated windshield sealing. The owner asked about accessing a floor drain plug.
Reported outcome: No leak source, drainage result or completed repair was reported.
The suggested plug location was not confirmed. Draining the floor alone would not establish that the water-entry problem had been repaired.
