Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Fuse Check

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown.

3. Wiper Switch Inspection

Remove the steering column cover using a socket set.
Disconnect the wiper switch connector.
Test the switch with a multimeter for proper continuity in all positions.
Replace the switch if it fails the test.

4. Relay Examination

Identify the wiper relay in the fuse box.
Remove the relay and test it for continuity with a multimeter.
If faulty, replace with a new relay of the same specifications.

5. Wiper Motor Testing

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector when the switch is activated.
If voltage is present and the motor does not operate, replace the wiper motor.

6. Reassembly

Reconnect all components in reverse order of disassembly.
Ensure all connections are secure and the cover is properly replaced.
