1. The main function is to defrost the rear windshield, the basic principle is that the heating wire of the glass laminated heating the glass, so that the temperature of the glass rises and evaporates the mist and water droplets on the surface.
2. Similar to the "heating resistance wire", multiple linear "heating resistance wires" are evenly distributed on the rear glass of the car.
3. Usually in rain, snow, fog weather, after the driver turns on the defrost/fog control switch (a certain position of the cab dashboard), the resistance wire is heated by electricity, the temperature of the glass rises, the frost or fog attached to the glass is melted by heat, melted into water droplets flowing down or volatilized into mist, so as to achieve the effect of defrosting and fog, so that the owner can clearly identify the rear driving conditions, reverse and other safe operations. Note: Do not accumulate items near the rear glass; It is recommended that the rear gear should not be applied.
