Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the battery to avoid electrical shocks.

2. Replace Blown Fuse

Locate the fuse box: Check the owner's manual for the exact location.
Remove the fuse: Use a fuse puller or pliers to extract the wiper fuse.
Inspect and replace: If the fuse is blown (wire inside is broken), replace it with a new fuse of the same amperage.

3. Repair or Replace Wiper Control Switch

Access the switch: Remove the steering column cover if necessary.
Disconnect the switch: Carefully unplug the connector from the switch.
Test continuity: Use a multimeter to check if the switch sends power when toggled. Replace it if faulty.

4. Repair or Replace Wiper Motor

Remove the wiper arms: Use a socket set to detach the nuts securing the wiper arms to the motor.
Unplug the motor: Disconnect the wiring harness from the motor.
Remove the motor: Unscrew the mounting bolts and take out the motor.
Test or replace: If the motor is faulty (no power or continuity), replace it with a new unit.

5. Reassemble Components

Reattach wiper arms: Align and secure them back onto the wiper motor.
Reconnect wiring: Plug all connectors back in.
Reconnect the battery: Ensure all components are correctly installed before re-energizing the system.
