Greetings, I have a NBC 2005 and a mysterious "soapy" wetness keeps appearing only on the floor board directly behind the driver's seat. This is the only spot on the floor that's wet. I've tested for leaks using a "wand" at the car wash. It hasn't rained in 5 days and I dried it all up last Tuesday. I checked under the rear seat for water bottles or whatever. I checked the spare tire well for water, nothing. Today, Friday, it's wet again. I'm stumped and welcome your insight!
