2005 E500 Wagon Rear Wiper Sprayer Issue
I've searched a bit on this but wanted to lay out my particular issue. Rear wiper works, when I push the button for the rear washer, the pump runs but no fluid comes out. I thought it was probably a blockage somewhere and just thought I'll get to it when I feel like tearing some stuff apart.
FF to today, played with it a bit more, still doesn't work but then I get a "Low Washer Fluid" message. Now I know there's no fluid leaking on the ground when the I press the sprayer but it's obvious that it's pumping fluid to somewhere and there's a leak INSIDE the vehicle.
Anyone have knowledge of where the washer lines run (previous cars have had the line run up the passenger A pillar to the back of the car but there aren't any stains in the headliner. Any help would be appreciated. Definitely not touching it until I have an idea of where to look.

No leak at pump, open spare tire area if you see washer fluid there check plastic union fitting located above subwoofer and Sirius module (if equipped).

Yep, the connection right by the subwoofer was disconnected. Wonder if someone was in there doing something with that sub and needed that disconnected and forgot about it. Hope the rust doesn't cause too many issues. Thanks so much for your help.

Old thread, but...this info saved me tons of hassle. I had the same symptom and I popped off the rear panel and sure enough that fitting had separated-quick and easy fix thanks to this thread-cheers!
