Kojem Back Panel Air Vent Relief Grille for 1999-2022 Silverado Sierra 13596856

The Back Panel Air Vent Grille is an important component in a car, located on the dashboard or top of the rear seat area. Its main function is to regulate and control the flow and temperature of air inside the car, in order to provide a comfortable driving and riding environment.

The ventilation grille is usually composed of a series of small holes or slits, allowing air to enter the car from the outside and, through adjustable design, allowing air to flow to the desired position for passengers. This helps to keep the air inside the car fresh and clean, preventing it from becoming stuffy and dirty.

The Back Panel Air Vent Grille can also adjust the temperature inside the car by adjusting its opening degree and direction. In hot weather, the ventilation grille can be opened to allow cold air to flow to passengers, providing a cool feeling. In cold weather, the opening degree of the ventilation grille can be adjusted to prevent excessive cold air from entering the car.
