Rear wiper does not work at all. front wipers work fine. rear washer works

SOURCE: Rear windshield washer motor works, but no fluid comes out

Rear washer may have it's own reservoir . Can you hear a pump humming when you activate the washer? Look in the under flooor compartment

You didn't mention any lost fluids so we can assume that no hapless mechanic has accidentally pulled any tubing loose from the supply. 
If, as in many cars, the path of the tubing connecting the washer fluid bottle to the jets on the cowl are visible, carefully pull one the tubes loose and have someone operate the washer to see if the pump is doing anything any more. You may be able to find the 'Y' junction where the tubes split off to feed the two jets.
The rear window washer has its own fluid supply and pump so is completely independent of the front.
If you find the pump working, then you will have to carefully poke a soft, small gauge wire, preferably copper, to try to clean the jets themselves. You probably have some small bits of something clogging the jets and it can help if someone is keeping the washer pump running while you try to clear them as the pressure will aid you.     
Worst case, the jets can often be replaced fairly easy and at a cost of a few dollars.

If it is the same as some other Chevrolets they have 2 pumps attached to the side of the washer bottle. 1 for rear and 1 for front windscreen

check for power at the wiper motor. If power at the wiper motor but no wiper action then replace the motor. if no power at the motor then use a jumper wire and put power to the motor. Does motor run? if so check for open circuit in the wire someplace.
