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 to prevent electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box (refer to the owner's manual for exact location).
Identify the rear wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it if blown (use a fuse of the same amperage).
Reinstall the fuse and reconnect the battery.

3. Test the Rear Wiper Motor

Reconnect the negative battery terminal.
Activate the rear wiper switch to check for operation.
If non-functional, proceed to remove the rear wiper arm by loosening the retaining nut with a socket wrench.
Disconnect the wiring harness from the rear wiper motor.
Use a multimeter to test for voltage at the motor connector when the switch is activated.

4. Replace the Rear Wiper Motor (if necessary)

If no voltage is detected, the switch or wiring may be faulty. If voltage is present and the motor is still inoperative, replace the motor.
Remove the mounting screws for the wiper motor using a socket set.
Install the new motor by reversing the removal steps.
Reconnect the wiring harness and replace the wiper arm.
