On the inside of the hood disconnect the washer hose from the nozzle, and squeeze the plastic under it together. Then push it up it should come out pretty easy.
On most vehicles, the same washer fluid reservour feeds the front and rear windshield nozzles - the one in the engine compartment.
Trace line back to nearest junction and replace line
A Chevy dealer or a wrecking yard.
the rear washer is fed from the same tank as the front washer-under the hood in the front right side.
I doubt the hose if clogged, but if it is, simply disconnect it and blow through it until it is clear. More than likely the spray nozzle at the end is clogged with car wax. Clean it out with a small pin or needle.
It is very easy ... Open the hood ... there is a long cover over the washer fluid tubing that connects to the nozzle .. so you have to take this cover off ... separate nozzel from tube . Insert new nozzle from outside of car . connect to tubing .. replace panel/cover and you are done !!!

the rear washer pulls from the front...fill the front end and the rear should work.
The issue could be a clogged sprayer nozzle, a faulty washer pump, or a broken washer fluid line. Check the nozzle for any debris blocking the flow, listen for the sound of the washer pump when trying to spray, and inspect the washer fluid lines for leaks or breaks. If necessary, clean or replace the nozzle, pump, or lines as needed.
Begin by removing the hose from your windshield washer pump. Remove the windshield washer pump wiring harness. Remove the windshield washer pump retaining bolts. Reverse the process to install your new windshield washer pump.
