Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Remove Wiper Arm

Use a socket set to remove the nut securing the wiper arm.
Gently lift the wiper arm off the spindle and set aside.
Repeat for the other wiper arm if necessary.

3. Access Wiper Motor

Remove the plastic cowl covering the wiper assembly (usually held by clips or screws).
Disconnect the electrical connector from the wiper motor.
Unbolt the wiper motor from its mounting bracket using a socket set.

4. Inspect and Test Wiper Motor

Use a multimeter to test the motor's resistance and ensure it meets specifications (consult repair manual).
If the motor is faulty, proceed to replace it.

5. Replace Wiper Motor (if needed)

Install the new wiper motor by reversing the removal process.
Secure it with bolts and reconnect the electrical connector.

6. Verify Operation of Wiper Control Switch

If the switch was found faulty, replace it by removing the steering column cover and disconnecting the switch connector.
Install a new switch and reassemble the column.

7. Reassemble Wiper Arm and Cowl

Reattach the wiper arms to their spindles, ensuring they are in the correct parked position.
Secure the wiper arms with nuts and tighten to specification.
Reinstall the plastic cowl over the wiper mechanism.
