Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Screwdrivers (flathead and Phillips)
- Wiring diagram of the vehicle (if available)
Safety Warnings:
- Disconnect the battery before working on electrical components.

2. Check the Rear Wiper Switch

Remove the trim panel surrounding the wiper switch.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when the switch is activated.
If the switch is faulty, replace it with a new unit.

3. Inspect the Fuse

Locate the fuse box in the vehicle (refer to the owner’s manual for location).
Identify the fuse for the rear wiper (usually labeled).
Remove the fuse and inspect it for continuity. Replace it if blown.

4. Test the Wiper Motor

Reconnect the electrical connector to the wiper motor.
Use a multimeter to check for voltage at the connector while operating the wiper switch.
If voltage is present but the motor does not operate, replace the wiper motor.

5. Inspect Wiring and Connections

Check the wiring harness leading to the wiper motor for any signs of wear or damage.
Repair or replace any damaged wires.
Ensure all connections are secure and free from corrosion.

6. Test the Washer Function

Inspect the rear washer fluid nozzle for clogs.
Activate the washer to see if fluid sprays.
If it does not, check the washer pump and its electrical connections.
