I filled my windshield washer container and I've noticed a very weak spray that's coming out. Any ideas why the sprayer would be so weak, it barely hits the bottom quarter of the windshield.

 

Is it below freezing? Mixed different brands?

 

The nozzles might be partially plugged. Do they both spray the same or is one weaker than the other. Also do you have the 360 cameras and if so does the front camera washer spray normal or is it weak as well?

 

By chance use any "Rain-X" branded fluid? That stuff has a habit of clogging nozzles.

 

I recently had my washer fluid pump motor replaced under warranty... so a failing pump is not out of the question.

 

Yes, I did. both nozzles are about the same strength. How do I unclog them?

 

soaking in a mild detergent and compress air is my recommendation. You do not want to be stabbing the inlet and outlet holes with any wire type instruments or run the risk of messing them up as they work on a venturi effect.

Stuff can also clog the inlet screen in the tank and lines.

 

Rain X Orange works great!! But don't mix it with anything else, add to empty tank.. Top off the tank before going in for service so they can't add any crap...

Rumor is if mixed with certain other types it turns to jell and plugs up intake..

In your case just disconnect the hose by tank, run the tank empty and refill with warm water, repeat till water is flowing good reconnect hose run it empty and fill with rain X, they should get better...

 

Sounds like partially clogged spray nozzles? FWIW, my 2016 washers have plenty of power, but Ford has finally (this is my 4th F-150) gotten the aim right (lower on the windshield) so they don't hose down the entire roof top

 

Found this in my perusing. It is a TSB for inoperative washers below freezing. The fix is a hose replacement.
