Greetings all,
While taking care of some overdue maintenance items (including changing out the wiper motor and linkage) on my 350SD, I came across a part that I cannot ID. It's in the air channel where the wiper motor/linkage resides. It's electrical in nature but I can't find this anywhere. Anyone know what this is? Here is a picture.
