Solution

1. Preparation

Gather tools: Socket set, multimeter, flathead screwdriver, and a replacement fuse if needed.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the rear wiper fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if broken, replace it with a fuse of the same amperage.

3. Test the Rear Wiper Switch

Locate the rear wiper switch on the steering column or dashboard.
Disconnect the switch from the wiring harness.
Use a multimeter to check for continuity across the terminals when the switch is activated.
If no continuity is found, replace the switch.

4. Inspect the Rear Wiper Motor

Access the rear wiper motor by removing the interior trim panel in the rear hatch area.
Disconnect the electrical connector from the motor.
Use a multimeter to check for voltage at the connector while the wiper switch is activated.
If voltage is present but the motor does not operate, replace the motor.

5. Reassemble and Test

Reinstall any panels or components that were removed.
Test the rear wiper operation by engaging the switch.
