Outer Limits 4x4 Board

Please need help urgent i have a 2001 dual cab 2 wheel drive ford courier and the driver's side floor has 2 -3 inches full of water from the rain. Has anyone had the same problem, will i have to take the windscreen out or could it be something else. Please help urgent?

I dont know anything about the couriers specifically, but one of the drain tubes that drains water from the cab air intake could have come adrift and draining water into the car instead of out the firewall.

found the prob if anyone has the same prob in the future! theres a big grommit that goes in through the firewall were the main wiring loom comes in and the water that runs down the left hand side of the windscreen goes straight into the front floor via that grommit! leaks like a farkin siv! gonna have to chock the bejesus out of it with sillycone! cant see any other way!
