Hello Fellow MB owners...
I have a 92 400E. When I turn on the AC on a hot day and it's been running awhile, OR if it rains really hard, there is a small but significant water leak by the passenger's side floormat. In otherwords, it looks like a drain or something is plugged causing it to drip, drip, drip onto the upper right/center of the floormat and it looks like it's comming from up under the dash somewhere. Does anyone know what I'm talking about and how I can fix this??? Thanks millions...
