Re: Are the rear wipers and rear washers wired together?...
I would check fuse, make sure it is good. I would pull panel and make sure you are getting 12 volts to motor, if you are it could be a bad motor, I would find out what one costs from your auto parts store, then call a reliable auto center, and get a repair quote from them, Please let me know what you find.

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.
Replacing parts just to replace them wont fix a bad wire or part. Better to use a voltmeter and ohn meter to check if your getting power to the wires. You may have a bad connection or bad switch on the column for the pumps. Without checking the circuits it will behard to tell what it is thats wrong. Find a wiring diagram and trace the wires and components.
First you need a wiring diagram, free at http://www.bbbind.com/free_tsb.html Then you need a DVOM - digital volt ohm meter to test the circuit . Then if your not familiar with automotive electrical systems testing ,go on youtube an check out Electric Testing Techniques You Need to Know Also having a factory diagnostic trouble shooting chart would also be usefull . You could just start replacing parts , you mite get lucky . The wiper motor is a high fail part , so is the switch ..You could find the fuse is blown ! But fuse's don't usually blow without a reason . Short to ground , low resistance . ( high current flow) Also knowing how they work and what all is involved in making them work.
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor module
• Windshield wiper motor
• Windshield washer pump motor
• FRT/WPR/WSHR 25A fuse
Wiper/Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls wiper motor operation. The windshield wiper motor is a 2 speed motor and is operated at low speed in all modes except HIGH. The accessory voltage supply circuit to the windshield wiper motor assembly is used to operate the wiper motor in all of the low speed modes. The accessory voltage supply circuit to the windshield wiper/washer switch is used to supply the windshield wiper switch signal circuits and the wiper motor high speed circuit.
When the wiper/washer switch is in the LOW position voltage is supplied through a 24K ohm resistor within the switch to the windshield wiper switch signal 2 circuit, and accessory voltage is supplied to the windshield wiper switch signal 1 circuit. The reduced voltage from the wiper switch signal 2 circuit and accessory voltage from the wiper switch signal 1 circuit causes the wiper motor module to close the wiper motor accessory voltage supply circuit to the wiper motor low speed terminal.
Windshield wiper/washer system MIST operation is identical to LOW operation except that the MIST switch is a press and release type. When the wiper switch is moved to the MIST position and released, low speed wiper motor operation is started and will continue until 1 cycle is complete. If the wiper switch is moved to the MIST position and held, the windshield wiper motor will operate in the LOW mode until the switch is released.
Don't the wipers work in any mode ?
1
Did you review the Wiper/Washer System description and operation and perform the necessary inspections?
YES - Go to Step 2
NO - Go to Symptoms - Wiper/Washer Systems

Does the test lamp illuminate?
YES - Go to Step 4
NO - Go to Step 13
4
Connect a test lamp from the accessory voltage circuit to the ground circuit of the windshield wiper motor.
Does the test lamp illuminate?
YES - Go to Step 5
NO - Go to Step 14
5
Connect a test lamp from the signal 2 circuit of the windshield wiper switch to a good ground.
Press the windshield washer switch.
Does the test lamp illuminate?
YES - Go to Step 11
NO - Go to Step 6
Let me know if you make it this far and i will send rest of diagnostic's
The switch is bad or the wiper motor cover ,electronics !
Turn the ignition switch to RUN.
Turn the wiper switch to OFF.
Disconnect the wiper/washer switch connector C201.
Do the wipers park? yes or no ?
if yes
Replace the wiper/washer switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle .
if no
Measure the voltage from connector C201 (vehicle side), terminal E2, to ground with a DMM.
Does the voltage measure greater than the specified value?
1.0 V yes or no ?
Replace the wiper motor cover. Refer to Wiper Motor Cover Replacement .

System OK
Go to Wiper/Washer System Check
Wiper shaft is stuck by rust (aluminium oxide). Remove wiper motor. Knock out wiper shaft with soft hammer. Clean shaft hole with similar size drill bit.
Check the wire connection just below the wiper motor. Its located on the passenger side by the washer fuild tank cap. With the wiper switch on delay, try moving the connection back and forth. Keep your hands clear of the motor arm. You may have to secure it in the right postion with a zip-tie.
When you purchase a wiper blade, the step-by-step instructions are included in the package. It will be a matter of carefully pulling up and out, then reverse the steps to install.
Fuse is good.. Checked power supply to the motor.. Have good power to motor.. So will replace with new motor. thanks
