Both front and rear washers use the same tank in the front of the vehicle the pumps are just at different levels. The rear is higher so it will go dry first. To test, swap the hoses from the front washer pump with the rear washer pump. When you turn on the front washers the rear window should get the squirt. If it still doesn't wet the window, check for a clogged washer nozzle, a disconnected hose under the rear compartment sill plate, or a disconnected hose in the tailgate. These are the most common.

They're both attached to their pumps on the side of the reservoir.

okay i took off the rear pump, the outlet that the pump connects to has power,(tested with metter) but when you plug the pump back in nothing happens, i brought a brand new pump too, i dont get it....let me know whats the next step i should go to...

thanks

The dark green wire has power when you hit the rear washers? Did you check the black wire for constant ground? Does the pump run and not squirt or not run at all?

MJTrippy

no the pump doesnt even turn on, but the outlet that the pump connects to has power, then when you hook both together, it lose's its power and doesnt do anything ( and you know when you hold down the wash button on rear? the wiper goes back n froth really fast, it doesnt to that when you hold the down the button.... it just does normal speed )

You don't want to connect both wires together. Hook a test light between the dark green wire and the black wire of the pump connector. Does it light when you push the button? If not, connect the test light between battery positive and the black wire. Does it light? If not, your ground for the pump is bad. The original ground goes to the radiator support, or you can run a new ground.
