Will Changing the Car Film Damage the Rear Window Heating Wires?

[BradyLee]

The possibility of damaging the rear window heating wires while changing the car film is relatively high, but it also depends on the situation. If the technician is skilled, the wires may not be damaged. Relevant details are as follows: Function of heating wires: The heating wires are similar to resistance wires. Their function is that during rainy, snowy, or foggy weather, when the driver turns on the defrost/fog control switch, the resistance wires are electrified and heat up, raising the glass temperature. The frost or fog attached to the glass melts due to the heat, turning into water droplets that flow down or evaporate as mist, thereby achieving the effect of defrosting and defogging. Function of car film: It mainly blocks ultraviolet rays, reduces heat, prevents glass from shattering and injuring people, and avoids glare. Additionally, based on the one-way transparency of the sun film, it can serve the purpose of protecting personal privacy.
