124 wagon sunroof drains

[Maxbumpo]

Has anyone found rear drains at the rear of the sunroof on a 124 wagon (or sedan, they probably are the same)? If they exist, how can I access them to make sure they are not clogged?

I've got water entry on the passenger side. I know that the sunroof seal needs to be replace (about $116 is the best price I can get from MB), but I'd like to make sure there isn't another problem or two problems before I start throwing $$ at it.
