Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver, and safety glasses.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove the wiper fuse.
Inspect the fuse for continuity; replace if it is blown with a new fuse of the same rating.

3. Inspect and Test the Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiper switch connector.
Use a multimeter to test for continuity when the switch is activated; replace the switch if no continuity is found.

4. Test the Wiper Motor

Find the wiper motor, typically located at the base of the windshield.
Disconnect the motor connector.
Use a multimeter to check for power at the motor connector while activating the switch.
If power is present but the motor does not operate, replace the wiper motor.

5. Inspect the Wiper Relay

Locate the wiper relay in the relay box.
Remove the relay and use a multimeter to check for continuity.
Replace the relay if it is faulty.

6. Check the Wiper Linkage

Remove the wiper arms using a puller tool if necessary.
Inspect the wiper linkage for wear, binding, or disconnection.
Lubricate or replace the linkage assembly as needed to ensure smooth operation.
