Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to ensure safety while working.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the correct fuse for the rear wiper using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it’s blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Rear Wiper Motor

If the fuse is intact, reconnect the battery.
Activate the rear wiper switch and check for voltage at the rear wiper motor connector using a multimeter.
- If voltage is present and the motor does not operate, proceed to replace the motor.
Remove the wiper arm by loosening the nut using a socket set.
Unscrew any mounting bolts securing the motor to the vehicle.
Disconnect the wiring harness from the motor.
Install the new rear wiper motor by reversing the removal steps; ensure it is securely mounted.

4. Check and Replace the Rear Wiper Switch (if necessary)

If the motor is functional and the wiper still does not work, the switch may be faulty.
Remove the steering column cover to access the switch.
Disconnect the wiring harness from the rear wiper switch.
Test the switch with a multimeter for continuity.
Replace the switch if there is no continuity when activated.
Reassemble the steering column cover after replacing the switch.
