Solution

1. Preparation

Gather tools: socket set, multimeter, flathead and Phillips screwdrivers, and replacement parts as needed.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to prevent electrical shocks.

2. Inspect and Replace Fuses

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the fuse for the windshield wipers using a fuse puller or pliers.
Check the fuse for continuity using a multimeter; replace if blown with a fuse of the same amperage.

3. Test and Replace Wiper Motor

Remove the wiper arms by loosening the retaining nuts with a socket set and pull them off the splines.
Locate the wiper motor, usually found beneath the cowl panel.
Disconnect the motor's electrical connector and use jumper wires to apply direct battery power to the motor; if it doesn't operate, replace the motor.
If replacing, remove the mounting bolts, install the new motor, and reconnect the electrical connector.

4. Inspect and Repair Wiper Linkage

If the wiper motor works, check the linkage by manually moving it and inspecting for any loose connections or breaks.
If damaged, remove the wiper linkage by unscrewing the mounting bolts and replace it with a new linkage assembly.

5. Replace Wiper Blades

Lift the wiper arms away from the windshield.
Release the old wiper blades from the arms by pressing the release tab and pulling them off.
Attach new wiper blades by sliding them onto the arm until they click securely in place.

6. Clean and Check Washer System

Check the washer fluid reservoir for fluid and fill it if necessary.
Inspect the washer pump for obstructions or damage; replace if faulty.
Test the washer system by activating it and ensuring fluid sprays onto the windshield.
