Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is parked on a flat surface.

2. Inspect and Replace the Fuse

Tools Required: Fuse puller or needle-nose pliers, replacement fuse (check owner's manual for specifications).
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the rear wiper (refer to the diagram on the fuse box cover).
Pull the fuse out and inspect it. If the metal strip is broken, replace it with a fuse of the same amperage.

3. Test and Replace the Rear Wiper Motor

Tools Required: Socket set, multimeter, screwdriver.
Locate the rear wiper motor, typically found under the rear hatch panel.
Disconnect the motor's electrical connector.
Use a multimeter to test for power at the connector when the wiper switch is turned on.
If power is present, the motor likely needs replacement. If no power, trace wiring back to the switch for continuity.
To replace the motor:
1. Remove the mounting screws using a socket set.
2. Carefully pull the motor out of its housing.
3. Install the new motor in reverse order, ensuring all connections are secure.

4. Test the Rear Wiper Switch

If the motor replacement does not resolve the issue, the rear wiper switch may be faulty.
Tools Required: Multimeter.
Remove the steering column cover to access the switch.
Test the switch with a multimeter for continuity when pressed. Replace if defective.
