Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the rear wiper fuse (refer to the fuse diagram on the cover).
Remove the fuse using a fuse puller and inspect it. If blown, replace it with a fuse of the same amperage.

3. Check Rear Wiper Motor

Reconnect the battery.
If the fuse is intact, access the rear wiper motor, usually located under the rear hatch panel.
Disconnect the motor wiring harness and use a multimeter to check for voltage when the wiper switch is activated.
If there is voltage and the motor does not operate, replace the rear wiper motor.

4. Wiring Inspection

If the motor is functional, inspect the wiring harness leading to the motor for frays or corrosion.
Repair any damaged wires with electrical tape or replace them if necessary.

5. Reassemble and Test

Once repairs are made, reassemble any panels or covers.
Reconnect the battery and test the rear wiper operation to ensure functionality.
