What to Do When Car Windows Frost Over in Winter Mornings?

[DonovanLee]

Here are solutions for frosted car windows on winter mornings: 1. Use the heater to defrost - start the car to warm up first, then turn on the heater after the engine reaches normal operating temperature; 2. Set the heater to maximum level, activate the defogging function along with rearview mirror and rear windshield heating; 3. As the car's interior temperature rises, the frost on the windows will gradually melt. Reasons for window frosting: 1. Frost mainly forms due to significant temperature differences between the car's interior and exterior - the parked car remains warmer than its surroundings. 2. When the car's temperature drops, moisture in the air condenses into water droplets on windows and subsequently freezes into ice crystals.
