Chrysler Repair: 2000 Chrysler Cirrus question, chrysler cirrus, 2000 chrysler cirrus

Question
I have a 2000 Chrysler Cirrus that the air conditioning recently quit working.  The fan does work, howver, the air conditioner blow warm air.  The interesting thing that I need info on is that under my front passenger seat, water has begun to surface, significant amounts of water- even when we do not have the vent, air or heat on.  The water jug is also going quickly.  There is a metal grate looking device under the seat. Can you tell me what this is?  I assume it is tied to the air conditioning.  Also, what do you foresee is the problem?

Answer
the ac system  can go in several different directions   could be low freon,compressor inop,restrictions in one of the lines.  The over flow and leaking water inside  could be related like a heater core leaking  and the metal grate   under the seat  I am not sure about that  I would haft to see what it is first.
