I read somewhere the winter freeze-proof fluid can make a slime when mixed with the summer bug cleaner fluid, and that's what I found to have plagued mine.
I could hear the pump churning, but could only get a dribble, then no fluid out of either the front windshield or rear glass. I heard the pump run, so that all worked, and I figured all 3 sprayers wouldn't clog simultaneously.
Shown in the photo Hamfisted posted above, that rubber gasket screen or filter doohicky that lies between the pump and the fluid reservoir was the problem was.
You can fix it by removing the passenger headlight assembly--2 screws on top, then pull/rock/pivot the housing; the side by the grill comes out first. Remove the headlamp wiring harness and turn signal bulb, and set it out of the way.
Next, remove the wiring harnesses from the washer fluid reservoir and tuck them up out of the way. You can leave the sprayer tubing connected to the pump.
Now, rock up/down and pull straight forward on the pump itself. As seen in the photo above, it just has barbs holding it in. then tuck the pump and tubing up out of the way.
Now you can use your fingers to pull that rubber plug/screen thing out of the reservoir. If you haven't emptied it, now will be the time you get a really clean spot on your driveway as the fluid rushes out!
Take the rubber stopper/screen and clean all the slime off. Then, reinstall everything.
Sadly, before I figured out I could access from behind the headlight, I tore into the wheel well and made substantially more work out of what turned out to be a pretty simple job.
