Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Check the fuse diagram to identify the rear wiper fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with one of the same amperage (typically 10A).
Reinstall the fuse.

3. Test the Wiper Motor

Reconnect the battery.
Use a multimeter to test the voltage at the wiper motor connector:
- Set the multimeter to the DC voltage setting.
- Engage the rear wiper switch and probe the connector.
- If voltage is present, the motor may need replacement; if not, check the wiring for damage.

4. Remove and Inspect the Wiper Motor

Access the rear wiper motor by removing the interior trim panel on the rear hatch.
Disconnect the electrical connector from the motor.
Remove the mounting screws using a socket set.
Carefully pull the motor out and inspect it for signs of water damage or corrosion.
If defective, replace with a new motor.

5. Reinstall and Test

Install the new wiper motor by reversing the removal steps.
Reconnect the electrical connector.
Reattach the interior trim panel.
Test the rear wiper operation to ensure proper functionality.
