I AM GETTING WATER ON THE PASSENGER SIDE FLOOR on 2010 Hyundai Sonata
I agree, check the heater box for plugged drain, or cracked broken case, under the dash area. You can run the A/C or the defroster, both use the evaporator to remove warm air from the cabin area. The condensation built up on the evaporator coil, melts and is designed to drain out under the car. Plugged drain or damage to this case will result in water on the front floor boards. Run the engine and the A/C or defroster watch under the dash for a leak, no water under car is a sigh of plugged drain, water only on the floor inside probably damaged case.
check ac condensate drain
