Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flat-head screwdriver.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box; refer to the owner's manual for the exact location of the wiper fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it with a new one if blown (typically a 20A fuse).
Reconnect the battery terminal.

3. Inspect and Test Wiper Switch

Remove the steering column cover using a flat-head screwdriver.
Unplug the wiper switch connector.
Use a multimeter to test for continuity across the switch terminals when activated.
If faulty, replace the wiper switch.

4. Examine and Test Wiper Motor

Access the wiper motor by removing the plastic cowl cover (if necessary).
Check for tightness of the motor connections and any visible damage.
Using a multimeter, check for power at the motor connector while the switch is activated.
If no power is present, trace back to the relay and wiring.

5. Replace Wiper Motor (if necessary)

If the motor fails the power test, remove it by unscrewing the mounting bolts.
Disconnect the wiring harness and remove the motor.
Install the new wiper motor by reversing the removal process, ensuring all connections are secure.
