Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle's 12V battery to prevent electrical shocks.

2. Check and Replace Wiper Fuse

Locate the fuse box, typically under the dashboard or in the front trunk area.
Identify the wiper fuse (refer to the vehicle's manual for the exact location).
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the wipers to see if they function.

3. Inspect and Replace Wiper Motor (if necessary)

If the fuse is good, remove the wiper arms by unscrewing the retaining nuts.
Carefully pull the wiper arms off the motor shafts.
Remove the cover panel (if applicable) to access the wiper motor.
Disconnect the motor connector and remove the mounting screws.
Replace with a new wiper motor, ensuring it is securely mounted.
Reconnect the motor connector and reattach the wiper arms.
Test the wipers for functionality.

4. Check and Replace Wiper Control Stalk (if necessary)

If the wipers still do not work, remove the steering column cover.
Disconnect the wiper control stalk connector and test for continuity using a multimeter.
If faulty, replace the control stalk with a new unit.
Reassemble the steering column cover and test the wipers again.
