What are the effects if the heating wire breaks during film application?

Impurities left on the air conditioning filter can mold and breed bacteria, which may harm the health of drivers and passengers, and even induce respiratory diseases. The following is relevant information about electric heating films: 1. Introduction: Low-temperature electric heating film is a semi-transparent polyester film that generates heat when electrified. It is made by processing and hot-pressing conductive special ink and metal current-carrying strips between insulating polyester films. During operation, the electric heating film serves as the heating element, radiating heat into the space, warming the human body and objects first. Its overall effect is superior to traditional convection heating methods. 2. Heating Principle: The heating principle of electric heating films involves the carbon molecular clusters in the heating element producing "Brownian motion" under the action of an electric field. Intense friction and collisions occur between carbon molecules, generating thermal energy that is transmitted externally in the form of far-infrared radiation and convection, with an electricity-to-heat conversion rate of over 98%. The action of carbon molecules causes the system's surface to heat up rapidly. When the electric heating film heating system is installed on walls (or floors), thermal energy is continuously and evenly transmitted to every corner of the room.
Last month I just went through this - a few rear window defroster wires broke during tint installation. These heating wires are mainly for defrosting and defogging, most useful when driving in winter. Once broken, the function is ruined - the rear window easily fogs up or frosts over, completely obscuring the rearview mirror, making it dangerously difficult to see vehicles behind while driving. I've actually had a minor collision because of this before - didn't notice an approaching car when turning, could've been disastrous. Worse still, broken wires may cause localized circuit shorts, leading to malfunctions or abnormal heating. My mechanic friend said this requires professional repair, usually using conductive adhesive welding or partial replacement - costly but absolutely necessary. When getting tints, always find skilled technicians who use soft tools and work carefully to avoid pulling the wires. Safety first - never underestimate these seemingly small issues.
