Solution

1. Preparation

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

2. Check and Replace Wiper Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Remove the cover and locate the wiper fuse (check the diagram on the cover).
Use a multimeter to check for continuity in the fuse.
If blown, replace the fuse with one of the same amperage rating.

3. Inspect and Replace Wiper Motor

Remove the plastic cover under the wiper arms (if applicable) using a screwdriver.
Disconnect the wiper motor electrical connector.
Unbolt the wiper motor from the mounting bracket with a socket set.
Install the new wiper motor by reversing the removal steps and reconnecting the electrical connector.

4. Test and Replace Wiper Control Stalk

Access the steering column by removing the trim pieces around it.
Disconnect the electrical connector from the wiper control stalk.
Use a multimeter to test the stalk for continuity.
If faulty, replace the stalk by unbolting it and installing a new one.

5. Verify Wiper Relay Operation

Locate the wiper relay in the fuse box.
Remove the relay and check for signs of damage.
Swap it with a similar relay to test operation; if wipers work, replace the faulty relay.
