Rear washer for wiper not spraying water wiper is ok can this be a fuse or can it be the pump

Sounds like you might have a bad multifunction switch. You can test the outputs of the switch to confirm.

Rear Wiper/Washer System Components
The rear wiper/washer system consists of the following components:
• Rear wiper/washer switch
• Window wiper module-rear
• Window washer pump-rear
• RR WIPER 15A fuse
• RR WPRB 25A fuse
Rear Wiper/Washer System Operation
The rear wiper module controls rear wiper motor operation. Battery voltage supplied to the module is used to operate the wiper motor in all modes and to return the rear wiper arm to the park position after the ignition is turned off. Accessory voltage supplied to the rear wiper/washer switch is used to supply the rear window wiper and washer switch signal circuits. In wiper switch positions 1 and 2 the wiper switch signal circuit voltage level to the wiper motor module determines the wiper motor delay interval. The rear window washer pump supply voltage circuit is used to provide the operating voltage for the rear washer pump for as long as the rear washer switch is pressed. The rear window washer switch signal circuit is used as a wash signal to the rear wiper motor module to operate the wipers during the rear wash operation.


Did you replace the rear wiper module ?

It's probably the washer pump motor , but testing is the best thing to do . Fuse #45 front an rear washer pump , plus there is two relay's . Both are controlled by the BCM - body control module . The fuse is located in the under hood fuse box .

fill the bottle or clean nozzle or replace pump or fuse

the washer fluid could be empty / the fuse for the wiper blew / the relay went bad /if you tried to use the wipers without clearing ice away you blew the fuse/ if you just put water in instead of washer fluid it's frozen/ if the wiper works and there is windshield fluid in the tank and not water and all fuses are good the pump motor for the fluid went and is easy to change

washer pump needs replaced

Can you hear the washer pump running when you operate the washer switch? The washer pump is in the bottom (side) of the washer fluid reservoir. You should hear it running. If not, you can disconnect the wire connector at the pump and use a test light to check to see if there is power and ground at the connector when you operate the switch. If there is power and ground, replace the washer pump motor. If there is no power or ground, you most likely have a bad washer control switch. (You have to replace the entire Multifunction Switch)

If you can hear the pump running, check for washer fluid pouring on the ground. If this is the case, you have a broken hose between the washer pump and the jets that spray on your windshield.

Also note that there is no way possible that your problem could be CAUSED by a fuse!

check hose for clogs if it's ok then you need to check the reservoir motor

The switch may not be making contact or wire to switch may have come off. If poss check voltage on the water pump for your rear screen. You may also have a bad earth.

The reservoir is the same one for the front washers. There are two electric pumps on the base of the reservoir (one for front and one for rear). You probably need a new pump. It is accessible behind the panel in front of the front right wheel.
