Can Warm Air Defog the Windows?

[KatherineLee]

Warm air can indeed defog the windows. When there is a significant temperature difference between the inside and outside of the car window, fog tends to form on the glass. To address this, after the engine coolant reaches normal operating temperature, turn on the warm air, set the air circulation to external mode to allow outside air to enter, reducing the temperature difference between the inside and outside of the glass, thus eliminating the fog inside the window. Then, switch to internal circulation to evaporate any remaining fog. Methods for defogging car windows: 1. Cold air defogging: Turn on the front windshield defogging button, activate the cold air, and direct it toward the windshield to quickly remove fog. 2. Purchase a defogging spray: Apply the defogging spray to the windshield in advance and wipe it clean to prevent fog from forming while driving.
