A couple of days ago, my wife noticed that the floor mat on the rear passenger side of her car was sopping wet. She thought perhaps a water bottle must have spilled or leaked, so she soaked up the water and dried out the mat. Today, the mat was wet again with about an inch of water accumulating only on the passenger side of the rear floor.
We have had no significant rain for more than two weeks; in fact, it’s been sunny and hot with temps in the 90s. There is no water on the front floor or the rear driver’s side floor. Due to the heat, we have run the AC, but it is working fine with no apparent leaks. There is no apparent leaking in the trunk or underneath the car. There are no apparent leaks from the radiator or hoses. Everything is working fine, except for the water on the rear passenger side floor. We can’t figure out the source of the water. Please help! Thanks.
The car is a 2006 4-door Toyota Camry LE with 199K miles on it.
