Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Check and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the rear wiper fuse using the diagram on the fuse box cover.
Remove the fuse with a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown with a new fuse of the same amperage.

3. Test the Rear Wiper Motor

Reconnect the negative battery terminal.
Use a multimeter to check for voltage at the rear wiper motor connector while someone activates the rear wiper switch.
If no voltage is present, further investigate the wiring and switch.

4. Inspect and Replace Rear Wiper Motor

If voltage is present but the motor does not operate, remove the rear wiper arm by loosening the nut with a socket set.
Remove the motor cover (if applicable) and disconnect the motor connector.
Unbolt the motor from its mounting points and remove it from the vehicle.
Install the new rear wiper motor by reversing the removal steps and reconnecting the wiring.

5. Reassemble and Test

Reattach the rear wiper arm and secure it.
Reconnect the battery terminal.
Test the rear wiper to ensure it operates correctly.
