The Problem

---

Modern vehicles rely on clear windshield visibility for safe vehicle operation, driver awareness, and the reliable performance of ADAS sensors and camera systems. During snow, freezing rain, and ice events, accumulation in the recessed windshield wiper park area can reduce wiping effectiveness even after the windshield itself has been defrosted.
Traditional windshield defrost systems are primarily designed to clear the windshield glass. However, the recessed wiper park region often receives limited thermal energy, allowing snow and ice to accumulate around parked wiper blades and mechanisms. This can reduce wiping performance, increase mechanical loads, and delay restoration of full windshield visibility during winter driving.
As vehicle electrification continues, minimizing additional electrical power consumption becomes increasingly important. Efficient use of existing HVAC thermal energy may provide an alternative approach to improving winter visibility while reducing the need for dedicated heating elements.Modern vehicles rely on clear windshield visibility for safe vehicle operation, driver awareness, and the reliable performance of ADAS sensors and camera systems.
