Solution

1. Preparation

Gather tools and materials. Disconnect the vehicle’s battery to prevent electrical shocks.
Tools Required: Socket set, multimeter, fuse puller, flathead screwdriver.
Safety Warnings: Ensure the vehicle is turned off and the key is removed from the ignition.

2. Inspect and Replace Wiper Blades

Remove the wiper arms using a socket set to loosen the nuts holding them to the wiper motor shaft.
Carefully lift the wiper arms off the windshield and replace them with new wiper blades if damaged.
Reinstall the wiper arms and tighten the nuts to the manufacturer’s specified torque.

3. Test and Replace Wiper Motor (if necessary)

Reconnect the battery and test the wipers. If they still do not work, proceed to check the wiper motor.
Disconnect the wiring harness from the motor and use a multimeter to test for voltage at the connector while activating the wiper switch.
If there is no voltage, trace back to the fuse and replace it if blown. Check for wiring issues.
If voltage is present but the motor does not operate, replace the wiper motor with a new unit.
Installation involves reversing the removal steps, securing the motor with bolts, and reconnecting the wiring harness.
