Solution

1. Preparation

Gather tools including a multimeter, socket set, and flat screwdriver.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and find the fuse related to the windshield wipers (refer to the fuse diagram).
Use a multimeter to check if the fuse is blown. If so, replace it with a new fuse of the same amperage.

3. Inspect and Test Wiper Motor

Disconnect the wiper motor's electrical connector.
Using a multimeter, check for voltage at the connector when the wiper switch is activated.
If voltage is present, connect the motor directly to a power source to test its functionality. Replace if it does not operate.

4. Examine Wiper Linkage

Remove the wiper arms using a flat screwdriver to gently pry off the caps and a socket set to remove the nuts.
Inspect the wiper linkage for any broken or loose connections.
If damaged, replace the linkage assembly as needed.

5. Replace Wiper Blades

Lift the wiper arms away from the windshield.
Press the release tab on the blade holder to detach the old blades.
Install new wiper blades by sliding them onto the arm until they click into place.

6. Check Washer Pump Functionality

Locate the washer pump, usually mounted near the windshield washer fluid reservoir.
Disconnect the washer pump's electrical connector and test for voltage with a multimeter.
If there’s voltage and the pump does not work, replace the washer pump.
