Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and screwdrivers.
Ensure the vehicle is in a safe, stable position, and the ignition is turned off.

2. Check and Replace the Fuse

Locate the fuse box (refer to the owner's manual for location).
Identify the wiper fuse and visually inspect it for continuity.
If blown, replace it with a fuse of the same amperage (typically 20A).
Recheck the wipers after replacing the fuse.

3. Inspect and Test the Wiper Control Stalk

Remove the steering column cover using a screwdriver.
Disconnect the wiper control stalk connector.
Use a multimeter to check for continuity when the stalk is activated.
If faulty, replace the wiper control stalk with a new one.

4. Test the Wiper Motor

Disconnect the wiper motor connector.
Using a multimeter, check for voltage at the connector when the wiper switch is activated.
If voltage is present but the motor does not operate, replace the wiper motor.
If no voltage, trace back to the switch or wiring for issues.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness and connectors for signs of wear, damage, or corrosion.
Clean any corroded connections with electrical contact cleaner.
Repair or replace damaged wires as necessary.

6. Check Wiper Linkage

Remove the wiper arms using a puller tool or appropriate method.
Inspect the wiper linkage for any signs of binding or wear.
Lubricate any moving parts or replace the linkage if damaged.
