Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Tools Required:
- Multimeter
- Screwdriver set
- Socket set
- Torque wrench
- Wire brush (for cleaning connections)

2. Check and Replace Fuse

Locate the fuse box; refer to the owner's manual for the exact location.
Remove the fuse for the rear wiper using a fuse puller or pliers.
Inspect the fuse for a break in the filament; replace if necessary.

3. Inspect and Replace Rear Wiper Switch

Remove the plastic cover surrounding the wiper switch using a screwdriver.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity in both positions (on and off).
If defective, replace the switch with a new one and reconnect the wiring.

4. Test and Replace Rear Wiper Motor

Locate the rear wiper motor; typically found under the rear hatch panel.
Disconnect the wiring harness from the motor.
Use a multimeter to check for voltage at the connector when the wiper switch is activated.
If no voltage is present, check for wiring issues. If voltage is present and the motor does not operate, replace the motor.

5. Reassemble and Test

Reattach any panels or covers removed during the process.
Reconnect the vehicle battery.
Test the rear wiper operation.
