Solution

1. Preparation

Gather all required tools and parts.
Park the vehicle on a flat surface and ensure the ignition is off.
Disconnect the 12V battery to prevent electrical shocks.

2. Check and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically located under the dashboard or in the front trunk.
Identify the wiper fuse using the fuse diagram.
Remove the fuse and inspect it for continuity; replace if blown.

3. Inspect and Replace Wiper Control Stalk

Tools Required: Screwdriver set, trim removal tools
Remove the steering column cover by unscrewing and gently prying it loose.
Disconnect the wiper control stalk from the wiring harness.
Replace with a new wiper control stalk if damaged or non-functional.
Reassemble the steering column cover.

4. Test and Replace Wiper Motor

Tools Required: Socket set, multimeter
Locate the wiper motor (usually under the cowl panel).
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the connector when wipers are activated; if no voltage, further electrical diagnosis is needed.
If the motor fails to work when powered directly, replace it.

5. Inspect and Replace Washer Pump

Tools Required: Socket set, container for fluid
Locate the washer fluid reservoir and pump.
Disconnect the pump from the reservoir and inspect for clogs or damage.
Replace the washer pump if it does not operate when tested.
