If the car window glass cannot open, it may be due to the following three common situations: 1. Glass vibration with abnormal noise. This indicates that the window regulator screws may be loose. 2. The window regulator is stuck. 3. All window regulators fail to work, losing the lifting function. Below is an introduction to car glass maintenance: 1. Proper use of windshield washer fluid: There are many types of windshield washer fluids available in the domestic market, mainly divided into three categories: summer windshield washer fluid, winter antifreeze windshield washer fluid, and special antifreeze windshield washer fluid. Summer windshield washer fluid is mainly used to remove insect residues from the mirror surface; winter antifreeze windshield washer fluid ensures that car components are not damaged when the temperature drops below -20°C; special antifreeze windshield washer fluid is mainly used in extremely cold northern regions, ensuring the car does not freeze even at -40°C. 2. Purchase glass insurance for your car: Glass breakage insurance is a commercial insurance where the insurance company compensates for the loss of the insured vehicle's glass breaking during use. Glass breakage refers to situations where only the windshield and window glass of the insured vehicle are damaged. 3. Apply window film to your car: In the scorching summer, heat-insulating film plays a significant role, not only blocking the blazing sun but also providing heat insulation and UV protection. Industry experts point out that heat insulation is one of the main reasons consumers choose window film. Additionally, the film's light transmittance and UV protection index are also important factors consumers should consider. However, many consumers have misconceptions when selecting heat-insulating films.
