I have a 2002 300M. I have an issue with a soaked drivers side floor. It doesn't seem to be a sunroof issue. It is only the front drivers section. Could it be the air conditioner drain backing up? If so, where exactly is it and how to I clear it? The only other issue I could possibly see it being is a windshield seal issue but it doesn't seem to wet up behind the peddles...just the floor. It is just water...not antifreeze.

Any help would be great. Thanks in forward.

I had the same problem on my passenger side door. Mine was a leak by the door I just took tape to cover where the water was coming in.
