I just took our 99 E300 (W210) out in the rain this past weekend and found we had a water leak coming in at the grab handle/coat hanger in the back seat passenger side. The wife was in that seat and found herself busy keeping dry.
I have read there are some sun roof drains that can get clogged. Can someone direct me to their location? Are there any other things I should be looking for that might be a source of this leak?
Thanks for the help.
