Why does the windshield light stay on?

The windshield light may stay on due to a few reasons, such as a malfunctioning sensor that detects whether the windshield is closed or open. Additionally, if there’s an issue with the vehicle's electrical system, such as a short circuit or a blown fuse, it might cause the light to remain illuminated. Another possibility is that the windshield wiper fluid reservoir is low, triggering the warning light. Finally, a simple software glitch or an unresolved alert in the vehicle's onboard diagnostics can also keep the light on.
