Windshield heating systems are designed to improve visibility by quickly defrosting or de-icing the windshield. These systems typically use electric heating elements embedded in the glass or warm air blown from the vehicle's heating system. By raising the temperature of the windshield, they help melt ice and clear fog, ensuring safer driving conditions. In many modern vehicles, windshield heating is integrated with the climate control system and can be activated with a simple button. Some advanced systems even feature heated wipers or defrosting vents that direct warm air specifically to the windshield area, enhancing effectiveness during cold weather.
