Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle’s battery to ensure safety while working on electrical components.

2. Fuse Inspection and Replacement

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

3. Wiper Motor Connection Check

Reconnect the battery.
Activate the rear wiper switch and use a multimeter to check for voltage at the wiper motor connector.
If there is no voltage, trace back to the switch and wiring for damage or disconnection.

4. Wiper Motor Replacement (if necessary)

If the wiper motor shows no signs of functionality, remove it:
- Unscrew the mounting bolts securing the wiper motor to the vehicle.
- Disconnect the electrical connector from the motor.
- Remove the wiper arm by unscrewing the retaining nut and gently pulling it off.
Install the new wiper motor:
- Position the new motor and reconnect the electrical connector.
- Secure it with the mounting bolts, tightening them to manufacturer specifications (typically around 7-10 Nm).
- Reattach the wiper arm and secure it with the retaining nut.

5. Rear Washer Nozzle Inspection

Inspect the rear washer nozzle for blockages or clogs.
If clogged, remove the nozzle and clean it with a pin or compressed air.
Reattach and test the washer fluid spray.
