Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock or short circuits.

2. Remove Rear Wiper Arm

Tools Required: Socket set, wiper arm puller (if needed).
Loosen the nut securing the rear wiper arm using the appropriate socket.
Gently pull the wiper arm off the splined shaft. If it is stuck, use a wiper arm puller for leverage.

Tools Required: Multimeter, screwdriver.
Disconnect the electrical connector from the wiper motor.
Set the multimeter to the DC voltage setting and connect the probes to the motor connector.
Activate the rear wiper switch and check for voltage. If there is no voltage, the issue may be with the switch or wiring.
If voltage is present, the motor may need replacement.

4. Replace Wiper Motor (if necessary)

Parts Required: New rear wiper motor.
Remove the mounting screws securing the wiper motor to the body.
Carefully pull the motor out, noting the orientation and position of any linkage.
Install the new motor in the reverse order, ensuring it is properly aligned and secured.
