i cant find mine either, is it possible that when the dealer steam cleaned the carpets, water got stuck under the mats? i turned on the AC full blast and ripped up the carpets to see where the leak is coming from. when i did lift up the carpet, water just drips from the carpet itself, but not from any source above that. i tried the tube that blows the cold air to the back seat, but no water found. i dried up all the water (well most) and im gonna drive all day with teh AC on and lift up the carpet again to see if theres anymore water. i really hope its just water from the cleaning.
