Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, fuse puller.
• Disconnect the car battery to ensure safety while working on the electrical system.
• Allow the vehicle to cool if recently driven.

2. Inspect and Replace Wiper Switch

• Remove the steering column cover using a socket set.
• Disconnect the wiper switch connector.
• Use a multimeter to test the switch for continuity when toggled in different positions.
• If faulty, replace the wiper switch with a new one.
• Reconnect the switch and reassemble the steering column cover.

3. Check and Replace Wiper Relay

• Locate the fuse box (check the owner’s manual for location).
• Use a fuse puller to remove the wiper relay.
• Test the relay with a multimeter for continuity; replace it if defective.
• Install a new relay and ensure it is seated properly.

4. Inspect Wiring and Repair

• Examine the wiring harness for any visible damage, fraying, or corrosion.
• Repair any damaged wires using appropriate electrical connectors or heat-shrink tubing.
• Ensure all connections are secure and free of moisture.

5. Reconnect Battery and Test

• Reconnect the battery terminals.
• Turn on the ignition and test the wiper function in all modes (off, intermittent, and continuous).
• Confirm proper operation and that wipers turn off as expected.
