Question on headlight washer....
Hi - while the car has been mostly sitting around in my garage these days, I noticed a puddle of washer fluid under the passenger side headlight. I took stuff apart today and noticed a couple things...
1) One place the fluid is leaking is right out the washer jet. So when I took that off the hose and checked it out, it looks like it should just have fluid going right thru it (if there is fluid coming up the hose)
2) Is the round thing that joins the inlet to the 2 outlets (drivers side and passenger side hose) just a Y connector or does that stop the fluid from coming out? The drivers side seems fine but not the passenger side hose (keeps filling up with fluid) - so I assume the Y connector doesn't do anything else but split the stream.
3) So does that just leave the pump itself? Where is it??
Thx in advance!!!

Did you every get this figured out?
I am currently dealing with this. I replaced the washer nozzles and the pump and still have fluid leaking from the passenger headlamp washer nozzles as the car sits. Did you end up replacing that 3way split/valve? Did that remedy your issue?
