How to Defog a Car in Cold Weather?
2 Answers
Methods to defog a car in cold weather are: 1. Locate the front window defogging mode, set the fan speed to maximum, turn on the AC switch, and then adjust the temperature to low; 2. Use the air conditioner's hot air for defogging. If the car has just been started, temporarily avoid turning on the air conditioner. Wait for the engine to warm up for 5 minutes until the water temperature rises, then start heating. Set the air volume to maximum and activate the front window defogging mode; 3. Adjust the air conditioner temperature to heating, rotate the air direction switch to blow onto the glass, and the fog will automatically disappear; 4. Prepare a defogging spray. Before traveling, simply spray it evenly on the surface of the car window glass and wipe it clean with a dry towel.
Driving in cold weather with foggy windows is really annoying. I found the most effective method is to start the car and let the engine warm up first, then turn on the heater to blow warm air at the windshield. Set the air conditioning to heating mode, adjust the airflow direction toward the glass, and turn it to maximum for a few minutes—the fog will clear. If the humidity inside is high, crack the windows slightly to let fresh air in and reduce condensation. I usually keep the windows clean and apply anti-fog spray regularly to prevent fogging. Remember, fog blocking your view is extremely dangerous—not clearing it before driving can easily lead to accidents. Also, replace the air conditioning filter regularly to avoid odors and blockages. In short, using warm air to clear fog is both quick and safe.
