Hello, I have a 1993 SR5. My avatar is the truck. I live in the pacific northwest where communist, socialist and rain are common. (No more politics, I promise).........whenever it rains very hard or for a long time my passenger floor get pretty wet. I'm pretty sure this isn't related to my AC since I don't get a chance to use it often up here. I'm looking for someone that has experienced this and fixed it. An old pillow case full of kitty litter does wonders but it's getting old having to fool with this. Thanks in advance..........
