Solution

1. Preparation

Gather tools: multimeter, socket set, flat-head screwdriver, Torx 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 Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the rear wiper fuse using the diagram located on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for a broken filament. Replace with an identical fuse if blown, ensuring it matches the required amperage.

3. Test and Replace Wiper Motor

Disconnect the negative battery terminal to ensure safety.
Remove the rear wiper arm using a flat-head screwdriver to pry off the cap, then a socket to remove the retaining nut.
Disconnect the wiper motor connector by pressing the tab and pulling it out.
Use a multimeter to check for voltage at the motor connector when the switch is activated. If no power is present, the switch or wiring could be faulty.
If power is present, replace the rear wiper motor by removing the mounting screws and replacing it with a new unit. Torque the screws to manufacturer specifications.

4. Reassemble and Test

Reconnect the wiper motor connector.
Reinstall the wiper arm and secure it with the nut, ensuring the arm is positioned correctly.
Reattach the negative battery terminal.
Test the rear wiper operation to confirm functionality.
