Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Socket set, multimeter, wire stripper/crimper, flat-head and Phillips-head screwdrivers, torque wrench.
Parts Required: Rear wiper motor (if replacement is needed), wiring connectors (if damaged).

2. Remove the Rear Wiper Arm

Use a flat-head screwdriver to gently pry off the rear wiper arm cap (if applicable).
Use a socket set to remove the nut securing the wiper arm to the motor shaft.
Carefully pull the wiper arm off the motor shaft.

3. Access the Rear Wiper Motor

Open the rear hatch and remove any plastic trim or covers that obstruct access to the wiper motor (typically secured with clips or screws).
Use a socket set to remove the bolts securing the rear wiper motor to the vehicle.

4. Inspect and Test the Motor

Disconnect the electrical connector from the rear wiper motor.
Use a multimeter to check for continuity in the motor. If no continuity is found, replace the motor.
If continuity is present, apply direct voltage to the motor to see if it operates. If it does not function, replace the motor.

5. Reassemble Components

Install the new or tested rear wiper motor and secure it with bolts, torquing to manufacturer's specifications (usually around 7-10 ft-lbs).
Reconnect the electrical connector to the rear wiper motor.
Reattach the rear wiper arm and secure it with the nut, then replace the wiper arm cap.

6. Test Functionality

Turn on the rear wiper switch to ensure proper operation.
Check for any unusual noises or malfunctions.
