wiper fluid sprayer

[j13smiley]

so the passenger side wiper does not spray any fluid. the spray nozzels both appear clean (not clogged). i'd like to check these out before winter comes and i might want to clean the windshield..

 

i popped the hood, looks like a single line runs from the resovoir to the driver side wiper. i'm assuming it then continues over to the passenger side. the lines are under the plastic trim... i'm assuming i should remove that and check the connections.

 

anyone got any other ideas of things i can check or look for when i start this?

So to put it another way, I'd find a way to verify if the sprayer is clogged. Maybe disconnect and back flow some water through it maybe? Then I would deinitely check all lines and connections under the hood. Not sure what else to check personally.

Once the head is unclogged you can disconnect the hose, add a very small amount of Vinagar to the water resivior, and run it through, then flush it out with straight water, it will remove the hard water deposits.

Try putting the hose into your mouth and blow through it. Chances are the nozzle is plugged though. You could also just take the nozzle off and clear it out. Don't use a pin or any other sharp object to clear it, that will make the hole too big, and it will not spray properly afterwards.

I've never tried it on this truck, but in the past I've disconnected the hose from the wiper arm, hit the washer to confirm it's pumping fluid.
