Hi... I recently found that the rear passenger carpet was wet. I check the the side near the door and it's dry. I removed the front carpet and the rubber insulator and found water... I got the water out and let it sit outside the rain. When I checked, I found water again so its not coming from the A/C. I guess it would come from the vents or the front door weatherstip or the windshield... Anybody have similar experience with the W124? any help is greatly appreciated.
