Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, flathead screwdriver.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect Wiper Components

Remove wiper arms:
- Use a flathead screwdriver to gently pry off the plastic cover at the base of the wiper arms.
- Use a socket set to remove the nut securing each wiper arm.
- Pull the wiper arms straight off the splines.
Inspect the wiper motor:
- Locate the wiper motor, usually found under the cowl panel.
- Remove any covers and connectors, and visually inspect for damage or corrosion.

3. Test Wiper Motor

Reconnect the battery temporarily:
- Use a multimeter to check for voltage at the wiper motor connector while activating the wiper switch.
If no voltage is detected, the wiper switch or wiring may need replacement.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Reassemble Wiper Components

Reinstall the wiper motor if it is functioning properly.
Reattach the wiper arms, ensuring they are aligned correctly on the splines.
Secure the nuts and reattach any plastic covers.

5. Final Steps

Reconnect the vehicle's battery.
Test the wipers in all operational modes to confirm proper functionality.
