Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and a small screwdriver.
Disconnect the vehicle battery to ensure safety.

2. Inspect the Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the rear wiper fuse (refer to the fuse diagram in the owner’s manual).
Use a multimeter to check for continuity. Replace the fuse if it is blown.

3. Check the Rear Wiper Motor

Locate the rear wiper motor, usually found under the rear hatch trim.
Disconnect the motor harness.
Using a multimeter, check for voltage at the motor connector when the wiper switch is activated. If voltage is present, the motor may need replacement.
If no voltage is detected, trace back to the switch and wiring for faults.

4. Replace the Rear Wiper Motor (if necessary)

Remove any trim panels blocking access to the rear wiper motor.
Unbolt the motor from its mounting bracket using appropriate socket size.
Disconnect the motor from the linkage.
Install the new motor by reversing the removal steps, ensuring all connections are secure.

5. Reassemble and Test

Reattach any trim panels that were removed.
Reconnect the battery.
Activate the rear wiper and washer to ensure proper operation.
