On a freezing winter morning, scraping ice from your car can feel like a battle. Yet while you struggle with the windshield and side windows, the rear window can quietly begin clearing itself. Those thin lines across the glass may look decorative, but they are actually an important safety feature.
The lines form the rear defroster grid, a simple but clever electrical heating system built directly into the glass. When activated, electrical current travels through the conductive strips, creating gentle heat across the surface. This warmth melts frost and helps clear fog from the rear window.
