Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and flathead screwdriver.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect the Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the wiper fuse and inspect it visually for any breaks.
Use a multimeter to test the fuse for continuity. If blown, replace it with a new fuse of the same amperage.

3. Test the Wiper Control Switch

Remove the steering column cover using a socket set.
Disconnect the wiring harness from the wiper control switch.
Use a multimeter to check for continuity across the switch terminals when activated. Replace the switch if defective.

4. Test the Wiper Motor

Locate the wiper motor, usually positioned at the base of the windshield.
Disconnect the motor's electrical connector.
Using jumper wires, connect the motor directly to the battery. If the motor operates, it is functioning; if not, replace it.

5. Inspect Wiring and Connectors

Visually inspect the wiring harnesses and connectors leading to the wiper motor and switch.
Look for frayed wires or corrosion.
Repair or replace any damaged wiring or connectors.

6. Check the Wiper Linkage

Remove the wiper arms using a flathead screwdriver to pry off the caps and unscrew the nuts.
Inspect the wiper linkage for any signs of wear or damage. Ensure it moves freely.
Lubricate or replace the linkage if necessary.
