Replaced wiper motor still not working fuse good power to motor is switch or module most likely cause

What u need to be looking at is the multifunction switch also known as combination, or turn signal switch if wiper selector is column mounted that is the on/off swich for wiper motor functions it also doubles as a variable resistance switch that sends signal to the (BCM) body control module but to start check fuses, then check for continuity or voltage at wiper motor is voltage is present replace wiper motor if no voltage is found check switch with a multimeter

Fuse #29 a 10 amp fuse . If the fuse is good test for power at the wiper motor . If no power there the switch or a connection or wiring issue is the cause . Of course if you have power to the motor the motor is bad or in a bind .

Did you check the fuse ? Do you hear the wiper motor running ? If the fuse is good you would need to test the electrical circuit for the wiper motor ,viewing a wiring diagram an then use a DVOM - digital volt ohmmeter to test
What body type is it ? Vin 6 or 3 could have a circuit breaker for power supply or fuse ,both are located in the rear fuse block .

Rear Wiper/Washer System Components
The rear wiper/washer system consists of the following components:
• Rear window wiper motor
• Rear window washer fluid pump
• Rear wash relay
• Rear window wiper/washer switch
• RR wiper 15A circuit breaker
• WASH 20A fuse
Rear Wiper/Washer System Controls
• Body control module (BCM)
• Liftgate control module (LGM)
• Rear wiper/washer switch

Here is how it is controlled

Rear Wiper/Washer System Operation
The rear window wiper/washer switch is an input to the BCM. The requested rear wiper mode is sent to the liftgate control module (LGM) by the BCM as a message on the serial data circuit, and the rear window wiper motor is controlled by the LGM. The switch power circuit to the rear wiper/washer switch is a 12-volt reference supplied by the BCM during ignition on, accessory or RAP power modes. The rear wiper/washer switch is a series of resistors and the switch position is determined by the voltage of the rear wiper/washer switch signal circuit to the BCM. The rear wiper/washer switch has continuity at all times and the BCM expects a rear wiper/washer switch signal voltage in all switch positions including OFF. The rear wiper motor is supplied battery positive voltage and ground. The LGM controls rear wiper motor operation through the rear wiper motor control circuit. The rear wiper motor control circuit is supplied a battery positive reference voltage by the rear wiper motor module and is pulse width modulated to ground by the LGM. The duty cycle of the pulse width modulation determines the rear wiper motor operating mode. The liftglass and liftgate ajar switches are inputs to the LGM and must be in an inactive state in order for rear wiper washer system operation to be enabled. When an ajar switch is active the LGM suspends wiper motor operation directly and sends the ajar switch status messages over the serial data circuit enabling the BCM to suspend washer pump operation. The rear window washer pump is controlled by the BCM through the rear washer relay. Battery positive voltage is supplied to the coil and switch sides of the rear washer relay. When the rear window wash request is active the BCM energizes the relay by grounding the relay coil through the rear washer relay control circuit. When the relay is energized battery positive voltage to the relay switch is supplied to the washer pump control circuit.

Your best bet mite be to have a qualified repair shop check for codes in the BCM or LGM

DTC B1017 or B3970

The rear wiper motor is supplied battery positive voltage and ground. The liftgate control module controls rear wiper motor operation through the rear wiper motor control circuit. The rear wiper motor control circuit is supplied a battery positive reference voltage by the rear wiper motor module and is pulse width modulated to ground by the liftgate control module. The duty cycle of the pulse width modulation determines the rear wiper motor operating mode.

What about the BCM is it ok, have the BCM module scanned for proper wiper control function.

Have you done a Probe Test on the vehicle? A Probe Light Tester can help you locate a short in your cars electrical system. To learn what a Probe Tester is and How to use it, watch the following video: https://www.youtube.com/watch?v=tXzKcEyIOq8

A wiring diagram doesn't show a relay, just a 25 amp fuse in fuse panel under driver's side of dash. Intermittent working is usually from a loose or poor or corroded connection, or the switch is old and tired, or the motor is old and tired.
Here is one way to check, if you have a test light: when the wipers are not working with wiper switch on high, and key is on, pull off the connector to the wiper/washer motor module (in the engine bay, on the firewall) and check if the purple wire has power. If it does, you probably need to replace the module. Inside the module is a park relay switch (to return wipers to down position when turned off) and a circuit breaker between the motor and ground.
If the purple wire does not have power when key is on and wipers on high, the connection is lost between the switch and the module, or the switch may be malfunctioning. The switch has 5 wires, white wire from 25 amp fuse (power in to switch), a pink wire (for the washer motor), a purple wire (high speed wipers), a dark green wire (low speed wipers), and a gray wire (for the park relay switch inside the wiper/washer motor module). If you see a yellow wire also at the module, that is part of the low speed wiper circuit (the dark green wire) coming from the park relay switch and then to the motor.
Good luck. Post back if further questions, or need more help.

The wiper control module is probably at fault ,without test that is just a guess . The wiper/washer switch is a input to the wiper control module. Do you know anything about automotive electronics an electrical systems ?

Hi.

Check if there is power to the wiper module when you turn on the wipers. If there is no power to the wiper module check multifunction switch, wiring and fuse. If there is power getting to the wiper module but the wiper motor is not energized, replace the wiper module. If the wiper module is energizing the motor but the motor does not start, replace the wiper motor. The wiper module is located in front of the wiper motor, under the hood. The module is held by screws, connected to the motor, and protected by a cover.

Regards.

CHECK FUSE IF FUSE GOOD.HOOK A JUMPER WIRE TO GROUND AND GROUND WIPER MOTOR.TURN WIPER SWITCH ON IF WIPERS WORKS YOU HAVE TO FIX GROUND CONNECTION. IF WIPER STILL DONT WORK.REMOVE THE COWL COVER.TURN WIPER SWITCH ON TO SEE IF POWER GOING TO WIPER MOTOR IF YES.REMOVE WIPER MOTOR HOTWIRE IT.IF WIPER MOTOR DONT WORK REPLACE IT.IF WIPER MOTOR DO WORK CHECK FOR BINDING OR DAMAGE LINKAGES.IF POWER NOT GOING TO WIPER MOTOR AND FUSE GOOD.WIPER SWITCH FAULTY OR IT HAS BROKEN WIRE FROM SWITCH TO WIPER MOTOR.

there are several things that can cause the wipers in your car not to work. if you have verified the fuses are good and verified power to your wiper motor, I would try disconnecting the negative battery cable for 15 minutes, then checking operation of the wipers. by the way, which fuses did you check?
