Hi all, my 2005 Gen 2 Prius is leaking windshield wiper fluid from the front passenger wheelwell when I pull the wiper spray lever. The fluid reservoir will hold fluid until this point, and then it empties itself entirely onto the ground once the lever is pulled. What would the problem be? The hoses themselves gone bad? Or something wrong with the reservoir? I have seen a YouTube video showing the reservoir and how the two fluid hoses connect to it, so I have some sense of how it works. Thanks in advance.
Well if the reservoir holds fluid but dumps it all on the ground, when you activate the sprayer - I would guess that your lines are rotted out. I wouldn't discount a bad reservoir either, since both plastics are of the same age. Bottom line is that you'll have to dig into it to see what's busted. If it's a lot of work to get down there; I'd replace the reservoir, motor, and tubing - so I wouldn't have to dig into it again. The question is what's your time vs money worth to you? YMMV
Shake the bolt off the top and the other one and lift the reservoir up twist the hoses and pull them away from the reservoir now with the reservoir loose with some fluid in it and the plug still connected but the hose is undone squirt the front windshield Just reach in and watch reaching your hand and twist the squirting thing or pull the squirting lever Do you see the fluid squared up towards the hood under the hood squirting up towards the hood that's raised now go walk around and look at what's happened either your pump is frozen and it's bad or it sticks or lines are bad plug the lines back up squirted again The pump should turn off when you let go of the stalk. So it just emptying out doesn't really make good sense like the pump would have to stay on and run until the jug is empty and then it should be squirting on the windshield or trying to if it's connected even with the split a little bit so then you can have your friend hold the stock back while you listen and watch You should see the leak pretty clearly but you may have to undo the jug so you can twist it a little bit.
