Hi this is my first post.
I just bought a used 1999 E320 4matic wagon (Glad to be part of the club!). The car didn't come with a manual and now all of a sudden the washer fluid doesn't work. Could it be a fuse? And if so where is/are the fuse box/boxes located?
Thanks!

 

some under the rear seatright side 2nd row seat, and under the hood on the left beside hood hinge under the black cover.

 

Thanks for the info! was able to change the fuse and now I'm ready for the rain!
