Re: front washer fluid does not pump, rear one does
Sounds like the pump is nacked. Or it may be a wiring earth fault. Find the wiring connector get a earth/Grong test light. Connect it to the positive and a good earth point on the car have some one work the stalk in the car and see if you got power if not it ll be the fuse, the pump or a busted wire in the line

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 !

Sounds like you may need to change the washer fluid pump. They do go bad. It's located inside the washer fluid reservoir, which is in the front of the passenger's side wheel well, behind the front bumper.
Yes there are two pumps located in the wiper fluid reservoir. If your in a bind, you can switch the plugs and small hose that go to them because they are both the same. The upper pump operates the back, and the lower pump operates the front. The back won't work until it gets replaced, but it beats driving backwards.
I'm pretty sure it's the same as the front washer, You can check by see ing if there are two pumps in the front washer resevoir, if not there is a possiblity that there is a bottle in the back, servicable by opening the rear door and looking at the walls behind the tires. I hope this helps
