Tools Required:

Multimeter
Socket set
Screwdriver set
Wire strippers (if needed)
Electrical tape

2. Replace the Rear Wiper 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 pliers.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Test and Replace the Rear Wiper Switch (if necessary)

Remove the switch panel by carefully prying it with a trim tool.
Disconnect the wiring harness from the rear wiper switch.
Use a multimeter to test for continuity across the switch terminals when activated.
If faulty, replace the switch with a new one and reconnect the harness.

4. Inspect and Replace the Rear Wiper Motor (if necessary)

Remove the rear wiper arm by unscrewing the retaining nut.
Unclip the motor cover to access the rear wiper motor.
Disconnect the wiring harness from the motor.
Using a multimeter, check for voltage at the motor connector when the wiper switch is activated.
If there is voltage but the motor does not operate, replace the rear wiper motor.

5. Reassemble and Test

Reattach the motor cover and wiper arm.
Reconnect the vehicle battery.
Test the rear wiper operation to ensure it functions correctly.
