Note
Inspect the area below the driver side of the instrument panel near the A-pillar for evidence of a water leak during the windshield water leak test. Carefully inspect the area around the instrument panel harness to body harness connector for evidence of a water leak. Visually inspect the instrument panel harness to body harness connector to ensure that it does not show signs of corrosion. Ensure the instrument panel harness to body harness connector does not get wet during the water leak test

1. Use an assistant to determine if a water leak is present. The assistant should sit inside the vehicle to inspect the vehicle for a water leak.

2. Perform the water test for 2-3 minutes to ensure the driver side A-pillar area of the windshield is exposed to enough water to determine if a leak is present.
