Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Multimeter
- Screwdriver set
- Pliers
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect the Wiper Control Settings

Turn on the vehicle and access the wiper settings through the central display.
Ensure that the wiper setting is not in the "off" position.

3. Check the Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to measure the voltage at the connector while activating the wipers.
- Expected voltage: 12V.
If no voltage is present, the issue may be in the control circuit or the switch.

4. Replace Wiper Motor (if necessary)

If the motor is faulty:
- Remove the windshield wiper arms using a puller or a flathead screwdriver to gently pry them off.
- Unbolt the wiper motor from its mounting location (usually requires a socket set).
- Disconnect the wiring harness from the motor.
- Install the new wiper motor by reversing the removal steps. Torque the bolts to the manufacturer’s specifications (consult the repair manual for specifics).

5. Inspect and Repair Wiring

If wiring damage is detected, repair or replace the affected sections using appropriate gauge wire.
Reconnect all connectors securely.

6. Test the Wiper System

Reconnect the battery and test the wipers by activating them from the control stalk.
Verify that both the wiper movement and washer fluid spray function correctly.
