Large amounts of Water cumulating under carpet in driver side front and back seat. The car is in good condition. Would this be from using the air conditioning and the excess water backs up into car.? Can here whistling too when using aircon. From the passenger side air vent. Does this whistling indicate a back up of water in the air vents. Because wasn't there before. If in fact it's a clogged air con water release hose. Where is the location to unblock it?

Look on the firewall behind the motor close to the bottom of the car and you'll see a little rubber black hose. It'll just pop off and sometimes they'll clog. To be sure you don't have coolant in the floors rub your hand in the water. If it's slimy it's probably coolant. Plain water will be squeaky on the hands
