Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Wiper Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Use a fuse puller to remove the wiper fuse and inspect it for continuity.
If the fuse is blown, replace it with a fuse of the same amperage rating (refer to the owner’s manual for specifications).

3. Test and Replace Wiper Motor

Reconnect the battery terminal and turn on the ignition.
Use a multimeter to check if the wiper motor is receiving power when the wiper switch is activated.
If there is no power, further investigate the wiring or switch.
If there is power and the motor does not operate, remove the wiper motor:
- Disconnect the motor wiring harness.
- Remove the motor mounting bolts using a socket set.
- Replace with a new wiper motor and reattach all connections.

4. Inspect and Repair Wiper Linkage

Remove the wiper arms by loosening the retaining nuts and lifting them off.
Inspect the wiper linkage for any signs of wear or breakage.
If damaged, replace the wiper linkage assembly:
- Remove the old linkage from the vehicle.
- Install the new linkage in reverse order, ensuring all connections are secure.

5. Replace Wiper Blades

Lift the wiper arms away from the windshield.
Press the release tab and slide the old wiper blades off.
Attach new wiper blades by sliding them onto the arm until they click into place.
