Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect Wiper Linkage

Remove the wiper arms using a socket set to unfasten the nuts holding them in place.
Carefully pull the wiper arms off the splines.
Check the wiper linkage for any visible damage or disconnection. If damaged, replace the linkage assembly.

3. Replace Wiper Motor (If Necessary)

If the wiper motor is tested and found faulty, proceed to replace it.
Remove the retaining bolts securing the wiper motor using a socket set.
Disconnect the electrical connector from the motor.
Install the new wiper motor by reversing the removal steps: connect the electrical connector and secure it with bolts, ensuring it is properly aligned.

4. Reassemble Wipers

Reattach the wiper arms to the splines, ensuring they are in the correct resting position.
Secure the wiper arms with their nuts and tighten to the specified torque (usually around 20-25 Nm).
Reconnect the vehicle battery.
