The Fastest Way To Defog Your Windshield

The Fastest Way To Defog Your Windshield

No matter the season, it's common experience foggy windows in your vehicle.  But did you know even in the winter, it's faster to defog your windows with the aid of your air conditioning, rather than full heat?

Fog on your windows is a build up of humidity, Just like a dehumidifier you may have in your home, air conditioning operates on the exact same heat-exchange principles.  This helps to dry up your foggy automobile windows faster!

Western GMC Buick Service Technician, Don S. said, "Your air conditioning compressor will work in temperatures low as -5 Degrees Celsius.  In the cooler months, if you combine your air conditioning with your heater, this acts as a rapid dehumidifier and clears your windows up faster!"

Want to try it for yourself?  Just do these four simple steps:

• Turn the heater on at full power
• Turn on the AC
• Turn off the inside air circulation (there’s typically a little button for this).
• Crack the windows open slightly

Still not a believer?  Check out this video from Mark Rober who puts it to the test!

One final defogging tip from Western GMC Buick Service Technician, John Y. - If you put your sun-visors down, it will help to trap the air being circulated which will help clear your windows faster.
