Disconnect the negative terminal of the battery to ensure safety.

2. Replace Wiper Blades

Tools Required: Flathead screwdriver, new wiper blades.
Lift the wiper arm away from the windshield until it locks in a vertical position.
Locate the release tab on the wiper blade where it connects to the wiper arm.
Press the release tab and slide the old wiper blade off the wiper arm.
Align the new wiper blade with the arm and slide it into place until it clicks securely.

3. Check Wiper Motor Functionality

Tools Required: Multimeter.
Reconnect the battery and turn on the ignition.
Activate the wiper switch to check for operation.
If not functioning, use a multimeter to test voltage at the wiper motor connector when the switch is engaged.
If no voltage is present, inspect the wiring and connections from the switch to the motor.

4. Inspect Wiper Fluid System

Tools Required: None.
Check the wiper fluid reservoir and fill with appropriate washer fluid if low.
Test the washer pump by activating the wiper fluid control; listen for the pump operation.
If the pump is silent, check the fuse for the washer system and replace if necessary.
