Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the ignition.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Fuses

Locate the fuse box (refer to the owner's manual).
Remove the fuse for the windshield wipers using a fuse puller.
Inspect the fuse; replace it if blown (use a fuse with the same amperage rating).
Reinstall the fuse and reconnect the battery.

3. Inspect and Test the Wiper Motor

Locate the wiper motor (usually positioned under the cowl).
Disconnect the electrical connector from the wiper motor.
Using a multimeter, check for voltage at the connector while activating the wipers.
If voltage is present but the motor does not operate, replace the wiper motor.
If no voltage is present, trace the wiring back to the switch, checking for breaks or damage.

4. Examine the Wiper Linkage

Remove the wiper arms using a puller tool.
Inspect the wiper linkage for any signs of wear, and ensure it is properly connected to the motor.
If the linkage is damaged, replace it with a new part.

5. Replace Wiper Blades

Lift the wiper arms away from the windshield.
Remove the old wiper blades by releasing the retaining clips.
Install new wiper blades, ensuring they are securely attached.
Lower the wiper arms back to the windshield.
