either the drain is plugged up and the evaporator housing is filling up with water or the housing is cracked and leaking.
it is also possible that it is draining properly out the drain but due to a missing rubber downspout and it siphon back along the drain pipe and back int to car under the mat.
remove the mat and check where exactly the leak is from
