I had a swimming pool in my car once.
It sounds like your drain lines are not connected to the end grommets.
You can remove the whole rubber grommet in the front door frame and see if the hose is connected to the back of it correctly, or just hanging inside the car body.
I found the rear lines were not connected to the grommet, water was pooling in the back of the car.
And the front was blocked also.
If you squeeze the nipple gently and water starts to run out, it means there is a blockage.
To get to the rear drains you need to remove the panel to access the tail lights, the pipe is brown. Follow the pipe down it connects down low under the bumper. There are 4 lines in total one to each corner of the car.
