Which button is the window defroster?

[ReaganFitz]

Due to different car models, the position of the window defroster button may vary, but it is generally located near the air conditioning controls. Introduction to the window defrosting function: 1. Purpose of window defrosting: To reduce moisture, fog, and frost on the front and rear windshields and exterior rearview mirrors, thereby improving visibility. 2. Necessity of window defrosting: When the dew point temperature is above zero degrees Celsius, fogging occurs; when it is below zero degrees Celsius, frost forms. Defrosting is essential for driving safety. 3. Precautions for window defrosting: Most internal combustion engines use engine coolant heat for heating. In winter, when temperatures are low, start the engine to warm up first. Only after the coolant reaches normal temperature will warm air be available. Before driving, use warm air to dry the windows to prevent fogging. If warm air is used for defrosting but the vehicle is driven before the windows are fully heated, the fogging may worsen.
