Welcome to NICO!
Wet floors are usually caused by clogged AC drains (or external leaks). Assuming you have all the factory glass and seals, its more likely to be the drain.
Check out the factory service manual to see where it might be.

I'm not sure if wiring runs along the driver's side floor or not, but I can imagine how frustrating it must be to have moisture in the cabin and no rear defroster... especially if that moisture is coming from the AC, which is stuck on.
