Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Wiper Fuse

Locate the fuse box in the vehicle (usually under the dashboard or in the engine compartment).
Remove the cover and find the fuse for the windshield wipers.
Use a fuse puller or pliers to remove the fuse.
Inspect the fuse for any signs of damage or breakage; replace if necessary with a fuse of the same amperage rating.

3. Test and Replace Wiper Motor

Locate the wiper motor, usually situated under the cowl panel at the base of the windshield.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the motor connector when the wiper switch is activated.
If no voltage is present, inspect the wiring harness for issues.
If voltage is present and the motor does not operate, remove the wiper motor by unscrewing the mounting bolts and disconnecting any linkages.
Install the new wiper motor and reconnect the electrical connector.

4. Check and Repair Wiring Connections

Inspect the wiring harness leading to the wiper motor and switch for any signs of wear or damage.
Repair or replace any damaged wires or connectors.
Ensure all connections are secure and free of corrosion.

5. Reassemble and Reconnect Battery

Reattach any components removed during the repair, ensuring all screws and fasteners are tightened properly.
Reconnect the vehicle battery.
Test the windshield wipers in all settings to confirm proper operation.
