Solution

1. Preparation

Gather tools: Phillips screwdriver, flathead screwdriver, multimeter, wire stripper, and electrical tape.
Ensure the vehicle is parked on a level surface, and the ignition is off.

2. Remove the Rear Wiper Arm

Use a flathead screwdriver to gently pry off the plastic cover at the base of the wiper arm.
Remove the nut securing the wiper arm using a socket set (typically a 13mm socket).
Gently rock and pull the wiper arm off the motor shaft.

3. Inspect and Test the Wiper Motor

Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for voltage at the motor's connector while operating the wiper switch.
- If there is voltage, the motor may be faulty.
- If no voltage, trace the wiring back to the switch.
If testing confirms the motor is faulty, proceed to replace it.

4. Replace the Wiper Motor (if needed)

Remove any retaining screws holding the motor in place and take out the old motor.
Install the new wiper motor in reverse order and secure it with retaining screws.
Reconnect the wiring harness.

5. Reassemble the Wiper Arm

Position the wiper arm back onto the motor shaft.
Secure it with the nut using a socket set, ensuring it is tight but not over-torqued.
Replace the plastic cover over the wiper arm base.

6. Test the Repair

Turn on the ignition and activate the rear wiper to confirm proper operation.
