What are the causes of grille baffle failure?

[DelEmmanuel]

One possibility is a malfunction of the water level gauge, and the second possibility is that large solid particles are blocking between the grille bars, slowing down the water flow. Here is relevant information: Characteristics of automotive grilles: It should be noted that in the overall design of a car, the role of the automotive grille is to protect and cool the radiator, hence it is also called the "air intake grille". The radiator is used to cool the engine. Once the engine fails to be cooled, it will overheat, leading to malfunctions and causing damage to other components due to high temperatures. Causes: Due to rain and cool weather, the grille plate does not open and remains in a closed state. When the vehicle passes through a puddle, water pressure is directed towards the grille plate, causing it to move without a computer command. When the grille plate moves, it activates the grille motor, which does not match the computer control system, resulting in a malfunction.
