There is a electric motor that pumps washer fluid . Located in the bottom of the washer fluid tank .
Wash Operation (Front and Rear Wipers)
The front and rear washer systems use the same windshield washer fluid pump. When either the front or rear wiper is in the washer position voltage will be supplied to one side of the windshield washer fluid pump (depending on whether it is front or rear), while the other side of the pump is grounded.
At this point, the windshield washer fluid pump sprays solvent onto the windshield. When the front or rear washer is activated, the BCM receives an input from the switch that is activated. The BCM will control the wipers while in the WASH mode. The BCM will control either the front wiper relay or the rear wiper relay to turn on the wipers. The windshield wipers operate at low speed for 3 swipes and returns to the park position.
When turning on the washers do you hear the motor run ? Have some one try it while you listen at the washer fluid tank ! These pump motors do go bad .
turn OFF the ignition.
Disconnect the harness electrical connector of the windshield washer fluid pump.
Connect a test lamp from the windshield washer pump control circuit to a good ground .
Turn ON the ignition, with the engine OFF.
Press the front washer switch.
Does the test lamp illuminate?
YES or NO !
Make sure you have water or windshield wiper fluid in the reserve (open your hood and add more, look for a blue plastic cap) if you hear it humming when you turn it on then the pump is working. Also check the little nozzles on the hood (one on each side) and see if they are clogged, stick a small safety pin into the holes and move it in and out to free up ant debris inside that may stop the water from squirting out
follow the windshield spray nasal water lie to the pump making sure the line is not broken, next do you hear the pump running when you spay the fluid, if not that the pump is faulty, if you do hear the pump running, more likely the windshield spray nasal is clog with debris; to unclog it try to use a clothes needle, poke around in it to see if you can clear the blockage, if not, replace will be the best idea, fairly cheap and easy to replace. those windshield tank and the pump does not have good filter on them and they tend to get clog up in the pump or the spray nasal.
