Missing Rear Windshield Wiper Assembly

Hi all,

I recently bought a 2013 Prius V to replace my trusty 2009 Prius (whose catalytic converter was tragically stolen). In all the excitement of getting a new car and looking over the important parts, I overlooked a relatively minor missing part.

The car is a salvage title with a replaced rear hatch. That doesn't bother me, especially at the low price I paid, but when the hatch was replaced, they neglected to install a new rear wiper assembly. Instead there's just a plug in the hole where the wiper should be installed. I'm not afraid to disassemble the hatch and put one in myself, but I am worried that the fluid line that runs to the wiper fluid reservoir is going to be missing. Does anyone have any experience messing with the rear wiper assembly, or possibly have photos of what a correctly assembled one looks like so I can at least figure out what all is missing and needs replaced?

I just took a look and at a minimum I'm definitely missing the motor. There's an electrical plug just dangling there unattached. When I removed the panel at the top of the hatch I found what looked like the termination of the fluid line, so at least it's nearby, assuming I correctly identified it.

Update: It turns out I'm dumb and that fluid line leads directly into the rear of the sprayer. As far as I can tell the whole rear wiper fluid system is still connected and present, it just won't spray for some reason. When I actuate it with the switch I can hear the pump motor run, but no fluid comes out (and yes, I checked the wiper fluid level and there's plenty). Maybe there's a clog in the line? The front wiper fluid sprays normally.

As for the actual wiper assembly, It seems I just need everything listed on this diagram and I'll be good to go:

Unless anybody is aware of something I'm not accounting for?

 

I soaked the spray nozzle with some Simple Green and stuck a safety pin in there, but to no avail.

 

I drive in all kinds of conditions all over the place, so it's worth fixing for me.

I'm considering pulling the fluid hose off at the rear hatch and blowing my air compressor through it. Simple as the concept is, I'd still have to remove the spoiler to access the hose with more than two fingers because Toyota engineers are sadistic baby-handed monsters. Anybody know if blowing out the line in that direction might have any unintended side effects? Like damaging the pump? I'd disconnect from the front and blow from there, but I'd have to remove the passenger side quarter panel to reach the base of the fluid reservoir where the hoses connect to the pumps. That seems like an excessive amount of work.

 

Update: The rear washer fluid sprayer just started working out of nowhere. It must have heard I was planning to hook it up to the air compressor and got scared.

 

I think you're probably right on all accounts. Glad I hit the magic number of minutes running the spray pump before trying anything drastic. It takes a surprisingly long time for the fluid to fill that line.
