There are 4 different diagrams depend on the year, but I can't tell which applies because all the notes and links are hosed. Now that I've spent some time piecing it together I think the right diagram is 80452000wb. In this diagram that relay is not mentioned. But to answer your question, the relay I was referring to is the Wiped area limitation control module.
It appears it is for another year. But I still can't understand why it would be involved. Sorry for the earlier confusion.

You changed the a control module in the trunk, I can't find anything else in common that you haven't checked. You have to get inside one of the door panels and see if voltage is making to the motor. Check fuse 8 instead of 10.
Just to make sure we are talking about the same module, in the diagram there looks like there are a lot of connectors on it. Does that match what you saw on the one you changed?


I've got to see about getting a new version cd from MB.
