Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, flat-head screwdriver.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect the Fuse

Locate the fuse box under the dashboard or engine compartment.
Remove the wiper fuse (refer to the fuse diagram) using a fuse puller.
Inspect the fuse visually for any signs of damage. Replace if blown.

3. Check the Wiper Motor Connector

Remove the wiper arm assemblies for easier access (use a flat-head screwdriver if needed).
Disconnect the wiper motor connector and inspect for corrosion or loose pins.
Clean the connector contacts with electrical contact cleaner and reconnect.

4. Test the Wiper Switch

Access the steering column by removing necessary panels.
Use a multimeter to test the continuity of the wiper switch.
If defective, replace the wiper switch with a new one, ensuring proper wiring connections.

5. Inspect the Wiper Linkage

Verify the wiper linkage by manually moving the wipers to check for binding or resistance.
If the linkage is worn or damaged, replace it with a new assembly, tightening bolts to manufacturer specifications.

6. Test the Wiper Motor

After reconnecting the motor, apply direct power to the wiper motor to see if it operates.
If the motor does not function, replace it with a new wiper motor, ensuring all connections are secure.
