2003 Mercedes-Benz CL500 Q&A
2003 Mercedes-Benz CL500 Question: Why is water accumulating on the floor behind the driver seat?
At first I thought a valet left the rear window open, I brought the vehicle for repairs, the carpets were removed and dried and all the electrical was replaced (apparently the majority of it runs underneath the back seat). Yesterday I noticed water had accumulated again. - new cl500 owner
poss heater core is leaking and running back there under the carpet. are you adding water to the cooling system? - globalhelper
No water in front pass side? Sun roof? Only after rain or car wash? - pushrod
