2000 TC Water Leak

Whenever it rains or I use a drive-thru car wash I find water has pooled on the driver side floor board. This happens even if the car is parked. I checked the sunroof drainage tubes and they seem to be fine as well as the window drain. I do not see any water coming down the walls around the interior near the floor board. I am at a loss as to where it is coming from.:runaround:

Seeing a water trail is difficult. Pull mats, carpet out. Dry completely. Get some really cheap baby/talc powder. Sprinkle on the vertical surfaces. Get a garden hose. When it starts to leak, you'll see a "snail trail" to follow. Start spraying water low and work your way up. (eng compartment, firewall etc. )
