Mystery water leak on drivers side floorboard

[thx0000]

2003 Hyundai Accent 4 door.
Well its been raining here in Portland Oregon non stop and this morning I went to get in my car and smelled a mildew odor so I took out the drivers floor mat and the carpet was soak. Then I laid back the carpet and that grey spongy covering thats under the pedals was soaked to the bone like a sponge. I did a test with a water by putting the hose on top of the roof of the accent and turning it on full bore and nothing leaked in the car .I sat in their for a good 5 minutes with the hose blaring down the windshield and door sides. I even took a jack and lifted the car up too see if there was any cracks or a rusty hole underneath but nothing . So Im completely stumped on this I do have A/C and the drain hose is clear since I have been using my defrosters and the A/C pump kicks on. Any advice?

Most of the time when that happens it is either the drain hose for the AC is plugged or has come loose OR there is a coolant leak in or around the heater core.

Might have to take the carpet out and leave it out for a while to assist in seeing where the water is coming from......and that would be a good idea anyway to be sure it is thoroughly dry too.

Don't know exactly on that model.
It is supposed to drain out underneath the car; hose is often near the firewall somewhere. Might be able to spot it with the car up on a hoist.

It is not at all strange to have only one footwell gettting wet because the heater/AC coil is usually a bit off center to one side.
