Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to prevent electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse connected to the rear wiper motor (refer to the owner's manual for the specific fuse location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace with a fuse of the same amperage if blown.

3. Test and Replace the Wiper Motor

Reconnect the battery and turn on the rear wiper switch.
Use a multimeter to check for voltage at the wiper motor connector.
- If voltage is present but the motor does not run, proceed to replace the wiper motor.
To replace the motor:
- Remove any covers or panels obstructing access to the motor.
- Disconnect the motor's electrical connector.
- Remove the mounting bolts using a socket set.
- Carefully remove the old motor from the vehicle.
- Install the new motor by reversing the removal steps.
- Torque the mounting bolts to the specified value (consult the service manual).

4. Check and Repair Wiper Linkage (if necessary)

Inspect the wiper linkage for any signs of damage or disconnection.
If damaged, replace the wiper linkage assembly.
Reassemble any covers or panels removed during the repair.
