Windshield Washer not working on (W213) E450 Wagon

I haven't been able to get the windshield washer to pump fluid (at all). I'm assuming you push and hold the single wipe button on the end of the stalk but nothing happens other than the wipers wiping.
I've been searching but can't find a fuse for the washers. Where is the fuse diagram for these cars? I believe it has (3) fusee boxes (under hood driver's side, passenger footwell and rear hatch). I did see a mention on a post that the washer pump is direct wired to 12v, is this correct?

It has fluid and to the best I can tell the jets are not clogged. What other troubleshooting can I do?
TIA

Your owner manual has information about the location of fuse panels for your vehicle otherwise log into your MBUSA.com account for a pdf of the manual. Inside each of the fuse panels there is a map of the fuse layour as well as to which circuit each fuse controls. Otherwise, your vehicle should still be under warranty so visit your MB dealer. I previously posted fuse diagrams for the W213 sedan. The wagon layour will be similar but slightly different.
