Noticed 4 inches of water in my rear passenger footwell this morning. After getting it all out, the floor felt like a water bed. Had to peel back the flooring to find rust soup. Another 2 inches of rusty ass water.

Any ideas?

ac condensate drain? turn on ac max, wait a few (10) minutes and check for a puddle or water drip under car

AC condensation will not fill a car floorpan with 6 inches of water. Even a completely plugged one. Unless it was running for like, a year maybe.

6 inches of water? I can see maybe 1 inch, but not 6. The water from the previous drive would be all dried up by the time the next drive starts, unless the car is used like a 24 hour taxi.

it does not dry out, only accumulates. too much humidity for any water to evaporate in an effectively sealed container.

after fixing my original issue I needed to wet vac under the carpets, then i left it with a blower with all the doors open, and even after that damp rid after i was sure the car was "dry" but my windows would still fog and it still smelled mildewed

Do you live in a dry climate? Since the condensation is just pulling moisture from the humid air around it, in some regions the volume of condensation can be mind boggling. I agree that it sounds like too much water, but only because I doubt that an old cop car has an AC working well enough. Even then, it's an option worth checking and rulling out.
