windshield wiper fluid

I can't get my windshield wiper fluid to pump out of the nozzle. What kind of cures do you suggest?

For me, troubleshooting is mostly a "divide and conquer" approach.

So, you do things like disconnect the output hose from the washer pump, and make sure it is pumping the fluid. If that isn't working then you check items from the pump back through the supply tank.

If that works then you disconnect the hose feeding the nozzles. If you get fluid there, then the nozzle(s) are clogged.

Basically, you want to prove that the pump is running and pumping fluid, and then concentrate on clogged/broken lines and nozzles.

That's my best shot.....

If the nozzles are clogged, you can use a small pin or needle to poke them (technical term) with and clean them out. It is also a good way to aim them if they are spraying in the wrong direction.

This may help in terms of aiming:

If you can't unclog the nozzles, new ones are cheap and easy to install.
