Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety during repairs.
Ensure the vehicle is parked on a flat surface.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the specific fuse for the rear wiper using the fuse diagram.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if blown, replace it with one of the same amperage.

3. Inspect and Replace Rear Wiper Motor

Remove the rear wiper arm by loosening the nut with a socket set and pulling it off.
Unscrew the motor assembly (typically held by screws or bolts).
Disconnect the wiring harness from the motor.
Use a multimeter to test the motor for continuity. If faulty, replace the motor.
Install the new motor by reversing the removal steps.

4. Check Wiring and Connections

Check the wiring harness for breaks, frays, or corrosion.
Clean any corroded connectors using electrical contact cleaner and a wire brush.
Reconnect any loose or damaged wires properly.

5. Test Rear Washer Pump

If the rear washer fluid is not spraying, check the washer pump.
Locate the washer fluid reservoir and disconnect the pump.
Apply direct voltage to the pump to see if it operates. If not, replace the pump.
Reconnect the pump and ensure the hoses are clear of obstructions.
