During heavy rain the floor in my '85 300SD get soaked. I read that the windshield seal could be a problem. The seal, or weatherstrip or whatever it is has gaps in it, I can stick a screwdriver inside, between the strip and the windshield. I was told that that is normal (??), is that true? Doesn't it have to be completely sealed up? Also, at the two bottom edges of the windshield there is some openings at both ends of the rubber seal/strip where a finger can be inserted beneath the windshield bottom, does that have to be sealed up?
Besides the sunroof, where else should I look for the source of this leaking, all floor wells get soaked.
Thanks in advance for any help. cp
