Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shock.
Ensure the vehicle is parked on a flat surface.

2. Inspect and Replace Wiper Fuse

Tools Required: Fuse puller or pliers, multimeter (for testing)
Locate the fuse box inside the vehicle (usually under the dashboard or near the driver's side).
Use the fuse puller to remove the wiper fuse and check for continuity with a multimeter.
If the fuse is blown, replace it with a fuse of the same amperage (usually 15A for wipers).

3. Test and Replace Wiper Switch

Tools Required: Multimeter, screwdriver
Remove the steering column cover to access the wiper switch.
Disconnect the wiper switch connector and use a multimeter to test for continuity.
If the switch is faulty, replace it with a new switch and reassemble the column.

4. Check Wiper Motor Connections

Tools Required: Socket set, multimeter
Locate the wiper motor, typically at the base of the windshield under the cowl.
Inspect the electrical connector for corrosion or damage; clean and secure any loose connections.
If necessary, replace the connector with a new one.

5. Test and Replace Wiper Motor

Tools Required: Socket set, 12V power source (e.g., battery or jumper wires)
Disconnect the wiper motor from the wiring harness.
Connect the motor directly to a 12V power source to test its functionality.
If the motor does not operate, replace it with a new wiper motor and secure it in place.

6. Reassemble and Test

After repairs, reassemble any components removed during the process.
Reconnect the battery and test the wipers to ensure they function properly.
