Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a flat-head screwdriver.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent electrical shorts.

2. Replace Wiper Fuse

Locate the fuse box (generally found under the dashboard or in the engine bay).
Remove the fuse for the wipers using the fuse puller or a pair of pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Replace Wiper Blades

Lift the wiper arms away from the windshield.
Release the wiper blade from the arm using the release tab.
Slide the new wiper blade into place and ensure it clicks securely.
Repeat for the other wiper blade.

4. Test Wiper Motor and Linkage

Reconnect the battery.
Activate the wipers to test for operation.
If still non-functional, remove the wiper arm and disconnect the motor connector.
Inspect the motor for any physical damage; replace if necessary.
Check the linkage for any disconnections or breaks and repair or replace as needed.

5. Repair Washer Fluid System

If the washer fluid does not spray, locate the washer pump.
Disconnect the pump and inspect for blockages or damage.
Clean any clogs and reconnect; test the system again.
