Where is the front windshield defogger button?

[TeaganLynn]

The defogging symbol for the front windshield is represented by three parallel upward-curved arrows inside a square frame. The defogging button is typically located at the bottom left corner of the air conditioning control panel. When the windshield fogs up, simply press the defogging button to activate the air conditioning defogging function. Physical principle of car cold air defogging: After the liquid refrigerant absorbs heat from the cooled object in the evaporator, it vaporizes into low-temperature, low-pressure steam, which is then sucked into the compressor and compressed into high-temperature, high-pressure steam before being discharged into the condenser. Physical principle of hot air defogging: When gas containing mist flows through the defogger at a certain speed, due to the inertia of the gas, the liquid droplets accumulated by the collision between the mist and the corrugated plates become large enough that the gravity of the droplets exceeds the combined force of the gas lift and liquid surface tension, causing the droplets to separate from the surface of the corrugated plates.
