There are a number of different possibilities like windshield or seam leaks but the first thing i would check is the vent at the cowl. It will have a drain at the bottom but if it gets filled with leaves or something, the water will back up into the AC housing.

? Just got it so perhaps history of this is impossible. Like HT said of many possible things I would first suspect the windshield and why: Look to see if it's original. Many "clones" just don't fit well and they should be marked like the other windows with something small frosted into a corner as a brand name.

If detailed up by a car dealership plain pressure washing might have been a bit too much for weak links for things that seal.

You may or may not find it with a garden hose either. Sneaky things can leak down while happening and not be found so easily.

Tough luck but you really need to dry it out including lifting up carpets as most do not dry out on their own well or much at all.

If any chance it's not rainwater try to find out in this case IMO not so likely engine coolant which would leave a unique odor,

If you eliminate the A/C drain then this is a common problem the part is available from GM a water deflector - I cannot find the TSB or PIT but your dealer will help. Maybe search- impala water leak - air inlet or cabin filter

Let us know what you find out

GM part is #15794785 BE advised this is surprisingly low priced for a GM part.
