Solution

1. Preparation

Tools Required:
- Screwdriver set
- Multimeter
- OBD-II scanner
- Pliers
Ensure the vehicle is parked on a level surface and turn off the ignition. Disconnect the negative battery terminal.

2. Inspect the Wiper Switch

Remove the steering column covers using a screwdriver.
Disconnect the wiper switch connector.
Use a multimeter to test the switch for continuity in various positions (low, high, intermittent).
If the switch is faulty, replace it with a new one.

3. Check Wiper Relay

Locate the wiper relay in the fuse box (refer to the owner's manual for exact location).
Remove the relay and test it with a multimeter for continuity.
If defective, replace the relay with a new one.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the wiper motor and switch for damage or corrosion.
Clean any corroded connectors with electrical cleaner and reconnect.
Ensure all connections are secure and intact.

5. Test Wiper Motor

Remove the wiper motor assembly from its mounting.
Connect the motor directly to a power source (ensure proper voltage) to test functionality.
If the motor fails to operate, replace it with a new one.

6. Replace Wiper Control Module (if necessary)

If all previous components are functioning, the issue may lie with the wiper control module.
Remove the module as per the service manual instructions.
Install a new module and reassemble the components.
