Can You Defog Without Using the Air Conditioner?

[CalebAnn]

You can defog without using the air conditioner. Defogging methods: If the front windshield fogs up, simply switch the air conditioner to defog mode. If the rear windshield fogs up, just turn on the rear windshield defogger switch, and the fog will dissipate quickly. The rear windshield has electric heating wires distributed across it, which are visible as horizontal lines. When the defogger switch is turned on, the heating wires warm the glass, causing the fog to evaporate. This method uses electricity for defogging, so it doesn't involve warm or cold air issues. Causes of car fogging: Car windows fog up when warm air inside the car meets the cold glass, causing condensation on the inside of the glass. Turning on the heater equalizes the glass temperature with the interior air.
