Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, flathead screwdriver, torx screwdriver.
Ensure the vehicle is parked on a level surface with the ignition turned off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse for the windshield wipers using a fuse puller or flathead screwdriver.
Check the fuse for continuity with a multimeter; replace with a new fuse if blown (typically 10A to 15A depending on the model).

3. Test and Replace the Wiper Motor

Locate the wiper motor (usually under the cowl panel).
Disconnect the electrical connector and inspect for corrosion or loose connections.
Use a multimeter to check for voltage at the connector when the wiper switch is activated. If no voltage is present, further diagnostics on the wiper switch or wiring may be necessary.
If voltage is present but the motor does not operate, remove the wiper motor by unscrewing the mounting bolts and disconnecting the motor linkages.
Install a new wiper motor by reversing the removal process and ensuring it is securely mounted.

4. Check and Replace the Wiper Relay

Locate the relay box (often near the fuse box).
Identify the wiper relay (check the diagram on the cover).
Remove the relay and test it by swapping it with another relay of the same type to see if the wipers activate.
If the wipers work with the swapped relay, replace the faulty relay with a new one.

5. Inspect Washer Fluid System

Check the washer fluid reservoir for adequate fluid levels.
Inspect the washer fluid pump connections and ensure they are secure.
If the pump is not operating, remove it from the reservoir and test it with a direct power source.
Replace the washer fluid pump if it fails to operate.
