Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace Fuse

Locate the Fuse Box: Open the driver-side door and remove the cover panel to access the fuse box located under the dashboard.
Identify the Rear Wiper Fuse: Refer to the fuse diagram on the cover or in the owner's manual to locate the correct fuse for the rear wiper (usually labeled).
Remove the Fuse: Use a fuse puller or pliers to carefully extract the fuse.
Inspect the Fuse: Check the fuse for continuity. If the metal strip inside the fuse is broken, it is blown.
Replace if Necessary: Replace the blown fuse with a new fuse of the same amperage.

3. Test Rear Wiper Motor

Reconnect Battery: Reconnect the negative terminal of the battery after replacing the fuse.
Activate Rear Wiper: Turn on the rear wiper switch to test if the wiper operates.
If Not Functioning: If the wiper still does not operate, proceed to test the motor.

4. Replace Wiper Motor (if needed)

Access the Rear Wiper Motor: Remove the rear trim panel in the cargo area to gain access to the wiper motor.
Disconnect Electrical Connector: Unplug the electrical connector from the rear wiper motor.
Remove Wiper Motor: Unscrew the mounting nuts holding the wiper motor in place and carefully remove the motor.
Install New Motor: Position the new wiper motor, secure it with mounting nuts, and reconnect the electrical connector.
