The passenger floorboard on my '03 RAV is filling up with water after I use the air conditioner. When I make a left turn, there is a sound of water moving from left to right in the dash; not so much when I turn right. A week ago, I crawled under the dash with a flashlight and could see water dripping from above. I disconnected the drain hose at the floorboard and water poured out. I blew out the pipe going through the floor and water started dripping underneath. It seemed OK for a few days but I had an inch of water today. Any suggestions of how to fix this or maybe a pic of the air conditioning system?
