What is the function of the horizontal lines on the rear car window?
2 Answers
The horizontal lines on the rear car window are electric heating wires, which can quickly defog and defrost. When external environmental factors cause frost or fog on the rear windshield, it directly prevents the driver from seeing the environment behind the vehicle. In such cases, the rear windshield heating function on the air conditioning panel can be activated to defog and defrost. These heating wires are also known as defrosters. During the initial stage of owning a new car, it is important to choose a qualified windshield film when applying it to the rear windshield. Using inferior films may cause the heating wires to malfunction. Additionally, when cleaning the car or performing other tasks, avoid using sharp objects to scratch these heating wires, as damage to the wires can result in the loss of the rear windshield heating function.
As a long-time car enthusiast, I'm very familiar with those horizontal lines on the rear windshield. They are actually electric heating wires that can quickly defrost and demist in snowy conditions, ensuring clear and safe rear visibility. I've studied automotive history - this design originated from early defrosters and now consists of precision resistance wires. With just a press of a button, electric current generates heat to melt ice and frost. It's particularly useful for driving in rainy or foggy weather, reducing the risk of reversing accidents. However, don't keep it on too long as it consumes significant power and may damage circuits. I always keep maintenance tools in my car to occasionally check wire integrity. Overall, this smart technology enhances convenience and is a feature both new and experienced car owners should utilize properly.
