Why Does My Windshield Keep Freezing While Driving?

Most car owners focus on how to prevent ice on windshields rather than finding the reasons behind such occurring. When you know the reasons, it becomes easier to prevent anything from happening rather than trying to fix it, not knowing what causes it in the first place!

In this section, we will discuss what causes a car windshield to freeze. Let’s explore:

Snow and Sleet

A snowfall can cheer you up if you are at the comfort of your home, but when you need to drive out, it won’t really excite you much! When coming down too fast, the snow and sleet can get paired with poorly functioning car windshield wipers that, as a result, can lead to a frozen windshield super fast!

So, to keep windshield from freezing, you must have a suitable defrost liquid on your car windshield or at least have a properly functioning wiper!

Failing to Warm Up the Car

If you want to know how to keep windshield from freezing while driving, you must understand that failing to warm up the car can lead to significant frosting issues!

When your car windshield is warmed up properly before you start with your journey, it will lower the chance of freezing up the glass! So, do not hurry for work or party; warm up the vehicle properly, and then set out!

Too Much Humidity Inside the Car

Are you still questioning yourself- why does my windshield keep freezing while driving even if I warm it properly?

Well, another major cause behind such freezing of the windshield can be the humidity inside the vehicle. When you drive your vehicle at a temperature that is above freezing, the humidity and the moisture inside the car can lead to a frozen windshield screen too soon!

At What Temperature Does a Windshield Freeze?

Now, as we know that driving at a temperature that is above freezing point can lead to a frozen windshield, many of us may wonder precisely at what temperature does water freeze on the windshield?

It may vary according to places, like in some areas, and the ice can become frozen at sub-zero temperature, whereas in some places, it can get frozen at extremely low temperatures only.

But in general, the snow gets frozen at a temperature below 32 degrees Fahrenheit. So, if you are wondering how cold does it have to be for windshield to freeze, then consider any temperature below 32 degrees Fahrenheit to be the cause behind it!

This happens because, in such less temperate weather, the metal and glass of the windshield lose the property to retain the heat and hence gives in to the coldness of the weather outside.

On a typical frost cycle that starts in the afternoon at about 45 degrees Fahrenheit temperature, the windshield gets heated and retains moisture throughout the day. It cannot retain the moisture at night, and water starts beading, causing it to freeze!

Thus, to stop ice from forming on windshield, you must warm up the vehicle heavily before setting off into the journey!

How to Keep Windshield from Freezing While Driving (9 Best Ways)

  1. I had just come down from the mountains and was driving to the denver airport. The heat was too high and I turned it down. About a half hour later my windshield suddenly was covered with ice which started from the bottom and quickly rose up the window. In 10 seconds or so the window was 3/4 obscured. In what turned out to be a stupid maneuver, I turned on the feature which clears windshields when driving, i. e. flicked the wiper control to spray fluid and turn the wipers on. Immediately I could see nothing. Within 15 seconds I raked a guard rail on the side of the road.

    Now I realize I could have just looked out the side window and done better.

    Do you have any idea what happened?
