TRACY THOMSON

:D Hi I'm new here so I was not sure where to post my question. I have a 96' GS300 whos passenger rear floor only gets wet from extended periods under a hose while washing. The last hard rain the passenger rear floor was soaked. The door seals properly and there is no evidence of it leaking through or under the door. Is there a drainage tube or channel that may be getting backed up? Though I am a girl I like to tinker around and learn about my car as much as possible Thanks in advance :D
