Solution

1. Preparation

Gather tools and materials, including a multimeter, OBD-II scanner, basic hand tools (screwdrivers, socket set), and a replacement wiper relay if needed.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Wiper Relay

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and locate the wiper relay based on the diagram on the cover.
Use a socket set to remove the relay from its socket.
If testing indicates the relay is faulty, replace it with a new one.
Reinstall the cover on the fuse box.

3. Repair or Replace Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiring harness from the wiper switch.
Test the switch for continuity; if faulty, replace it with a new switch.
Reconnect the wiring harness and reassemble the steering column cover.

4. Inspect Wiper Motor

If the wiper relay and switch are functioning, inspect the wiper motor.
Remove the wiper arms using a puller tool if necessary.
Disconnect the motor wiring harness.
Apply power directly to the motor terminals using jumper wires; if it does not operate, replace the motor.
