This is the second time that I've had water in the TL. The first I pulled up the carpet and sucked out about a 1/2 gallon or more of CLEAN standing water from the drivers side front and rear pan. I lifted the car up on a lift and didn't find anything out of the ordinary. I ripped out the carpet and seats to dry out the car.

Now I've done some searches, and i found that it may be the Condenser drain or Sunroof drain. But I didn't see any location information. I need some help on this one, I'm trying not to give up.

 

So your getting moisture in the car. IS it raining when this happens? or just randomly. You may want to keep the interior of the car out and get a few garden hoses and start hosing the car down looking for where the water is coming in. It may be a plugged drain hose or bad seal or grommet somewhere. the condenser is on the passenger side and one would assume thats where the water would be if it was that.

I believe the sunroof drain goes to the rear of the car into the trunk area before it goes out.
