Water on floor
I hav a 1980 300 SD and I have discovered a major leak on the floor in the back behind the drivers seat. All the mats were soaked and water was laying in a pool under the mats. I checked around the door seals and the rain doesn't seem to be coming in from there. A hole in the floor seems unlikely as there is too much pooling of water there. Could there be some connection between this and apipe that drains the water from the sunroof. Where is the drain outlet located. Could it be plugged. Otherwise I may have to take out the front seat.which is non powered. Is that a difficult job? I would like to track this leak down and would appreciate any suggestions. I live on Vancouver Island and we are getting tons of rain right now. Thanks.
