water leak in 300ce e320 convertible
 

Hi. in my 1993 300ce convertible water accumulates behind the passenger seat when it rains. Only on that side. I had a similar problem behind the driver's seat in a 300e, and fixed it by replacing the drain hose from the windshield, the material-coated "hose" accessible by removing the side carpeting next to the gas pedal. Is this the same problem? If so, any tips on accessing that hose on the 300ce? Thanks.
