Windshields Should be Cleared in the Winter

It is a part of winter driving that happens all too often, you will have to get ice off the outside of the windshield, but inside a fog clouds your vision. Clearing a foggy windshield up is not as simple as turning on the defroster. Keeping your window clear in the winter is all about balancing the warmth and moisture inside your car with the cold, dry air on the outside. Too much moisture, and your cabin will reach the dew point, which leads to fog on the window. Until the inside is dry, your glass will remain fogged. There are some tips you can do to help eliminate this issue when driving.

You will want to make sure the windshield is clean and dirt is removed. Dirt on the inside of your windshield gives moisture more to cling to. Use a good glass cleaner to remove any film or dirt that may have collected on your windshield. Before turning on the defroster, give your car’s heating system a few minutes to warm up. The air duct temperature needs to reach about 130 degrees before the defrost mechanism becomes effective, but make sure not to leave your car when it’s operating, because your car can get stolen.

Once you turn the defroster on, turn it up high. You need to cover 90 percent of the glass with air in very poor weather, like freezing rain or snow and very cold temperatures, in order for the defroster to work effectively.

Make sure that you are taking in fresh air from the outside of the car, if it’s snowing, clear the outside vents before pulling out of the driveway, by turning the recirculate button off. If you are recirculating air it can mean that moisture never leaves the cabin and de-fogging the windows becomes very difficult, if not impossible. If the defroster does not work for your vehicle, make sure to schedule an appointment and we can inspect the vehicle for you.
