Solution

1. Preparation

Tools Required: Multimeter, OBD-II scanner, socket set, flat-head screwdriver, and a new wiper relay (if needed).
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace the Wiper Relay

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and find the wiper relay (refer to the owner's manual for exact location).
Test the relay using a multimeter to verify it is functioning correctly.
- Set the multimeter to 'Ohms' and check for continuity.
If the relay is faulty, replace it with a new one.
Reinstall the fuse box cover and reconnect the battery.

3. Examine the Wiper Motor and Wiring

Remove the wiper arms by loosening the retaining nuts with a socket set.
Disconnect the electrical connector from the wiper motor.
Inspect the motor for any visible damage or corrosion.
If the motor looks intact, check the wiring harness for any signs of wear or damage.
If necessary, replace the wiper motor, ensuring all connections are secure upon installation.

4. Test the Wiper Switch

Reconnect the wiper switch and test its operation.
If it is still not working correctly, consider replacing the switch.
To replace, remove the steering column cover and unscrew the switch from its position.
Install the new switch and reassemble the steering column.
