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 found under the dashboard or in the engine compartment.
Identify the fuse for the rear wiper using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for signs of a blown filament; if blown, replace it with a fuse of the same amperage (usually 15A).
Reinstall the fuse.

3. Inspect and Test the Wiper Motor

Remove the rear wiper arm by loosening the nut using a socket set.
Disconnect the electrical connector from the wiper motor.
Using a multimeter, check for power at the connector while the wiper switch is activated.
If power is present, connect the motor directly to a 12V power source to see if it operates; if not, the motor needs replacement.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the rear wiper motor for frays or breaks.
Clean any corrosion from connectors using electrical contact cleaner.
Ensure all connections are secure.

5. Reassemble Components

If the motor was replaced or repaired, reconnect the electrical connector and reattach the wiper arm.
Tighten the wiper arm nut to manufacturer specifications (typically around 10-15 Nm).
Reconnect the negative battery terminal.
