the A/C condensate drain tube is most likely clogged,and has been clogged for a while.check the cabin air filter and see if it is wet also. it is under the hood, under and just behind the blower fan. It is not a 'tube' per say, but rather a plastic black square formed tube, that snakes a bit downward, with a rubber flap on it's downward end. That flap faces the passenger's wheel, and has a weighted portion on it that keeps the flap closed. I'm having to clean mine out right now, and am finding maple seeds and mud (possibly wet dust) blocking the water from escaping.THIS IS AN OLDER MODEL,YOURS MAY BE DIFFERENT!if you have that much water,your heater/evaporator box must stay full from being stopped up.i'm going to send you a couple of links to copy and paste,then watch the videos.may not be like yours,but works the same,unless you have a windshield seal,roof or door seal leaking,which i don't know,but anyway read and watch the videos,see how it works!watch both videos,the 2nd one is a little better!
