Why is there frost inside the car window?

[LeLucia]

Here are the reasons for frost formation on car glass: 1. Frost on car windows mainly occurs due to the significant temperature difference between the inside and outside of the vehicle. After the car is parked, its temperature remains higher than the surrounding environment. 2. As the car's temperature begins to drop, moisture in the air condenses into water droplets on the windows, which then freeze into ice crystals. Here are solutions to remove frost from car windows: 1. Use the heater to defrost. First, start the car to warm up the engine, then turn on the heater once the engine reaches normal operating temperature. 2. Set the heater to maximum power and activate the defogger function along with the rearview mirror and rear window heating features. 3. Once the car reaches the desired temperature, the frost on the windows will gradually melt.
