Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and a replacement fuse if necessary.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check Wiper Control Settings

Power on the vehicle.
Access the touchscreen controls and navigate to the wiper settings.
Ensure the wipers are set to "Auto" or "On." Adjust settings as needed.

3. Inspect and Replace the Fuse

Locate the fuse box; refer to the owner's manual for its location.
Identify the wiper fuse using the fuse diagram.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity using a multimeter. Replace if blown with an identical fuse (typically 15A).

4. Examine the Wiper Motor and Connections

Remove the wiper arms by loosening the nut with a socket.
Disconnect the wiring harness from the wiper motor.
Inspect the wiring for frays or corrosion. Repair or replace as necessary.
Reconnect the motor and test by applying 12V directly to the motor terminals to check if it operates.

5. Replace the Wiper Motor (if necessary)

If the motor does not work when powered directly, it may need replacement.
Disconnect the negative battery terminal to prevent any electrical shorts.
Remove the old motor by unscrewing the mounting bolts.
Install the new wiper motor, ensuring it is securely fastened.
Reconnect the wiring harness and the negative battery terminal.
