What are the horizontal lines on the rear car window for?

[OLaura]

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 called defrosters. Introduction to car window electric heating wires: 1. During the new car phase, when applying a rear windshield film, it is essential to choose a qualified windshield film. Using inferior quality film may cause the heating wires to malfunction. 2. During vehicle cleaning or other maintenance, avoid using sharp objects to scratch these heating wires, as broken wires will result in the loss of the rear windshield heating function.
