Your windshield is a very important component of your car because it allows you to scan the road for potential hazards. That’s why a windshield that fogs up constantly can be a serious issue. In this post, we discuss some reasons why your windshield is always foggy and offer some solutions.
Why Is My Windshield Always Foggy?
The first thing to understand is that what we call fog is actually moisture that builds up on your windshield. In some cases, the moisture comes from the air you exhale (like when kids fog glass with their breath), but there are other sources as well. Let’s take a look.
Difference in Temperature
In most cases, the interior of your windshield is foggy because there’s a temperature difference between the interior of your car and the windshield itself.
For example, if you turn up the heat on a winter day, the air inside your car will be warm but the windshield will be cold because it’s exposed to the chilly air.
As a consequence, condensation will form on the glass. To solve this, you can crack a window open just a little for a few minutes.
Your Windshield May Be Dirty
In some cases, a foggy windshield may be just dirty. Plus, keep in mind that pollutants on the glass can make it more prone to fogging up.
To prevent grime from obstructing your vision, clean your windshield thoroughly and regularly with ammonia-free products specifically formulated for automotive glass.
Heater Core Leak
If there’s no noticeable temperature difference and your windshield keeps fogging up even after cleaning it, then the reason may be more complex.
Heater core leaks are a common reason for persistent fogging issues.
The heater core is a smaller version of the radiator used to warm the cabin of a car. When the coolant contained in the heater core leaks into the cabin, it evaporates and fogs up the windows of your car.
If you suspect that your vehicle has a heater core leak, take it to a specialist to determine whether the heater core can be repaired or it needs to be replaced.
