Solution

1. Preparation

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

2. Check and Replace the Fuse

Locate the fuse box: Refer to the owner’s manual for the exact location.
Remove the fuse: Use a fuse puller or pliers to remove the rear wiper fuse.
Inspect the fuse: Check if the metal strip inside the fuse is broken. If it is, replace it with a new fuse of the same amperage.

3. Replace the Wiper Relay (if necessary)

Locate the relay: Find the rear wiper relay in the fuse box or in the engine compartment, depending on your model.
Remove the relay: Gently pull the relay straight out of its socket.
Install the new relay: Push the new relay into the socket until it is seated properly.

4. Test and Replace the Wiper Motor (if necessary)

Access the rear wiper motor: Remove the interior trim panel in the rear hatch to expose the motor.
Disconnect the motor: Unplug the electrical connector from the wiper motor.
Apply direct power: Use jumper wires to connect the motor directly to the battery to see if it operates.
- If it works, check the wiring; if it doesn’t, replace the motor.
Install new motor: If replacing, remove the mounting screws, install the new motor, and reattach the electrical connector.

5. Reassemble and Test

Reattach the trim panel: Secure the interior trim back into place.
Reconnect the battery: Reattach the negative battery terminal.
Test the wiper: Turn on the rear wiper to confirm it functions correctly.
