If your windows keep fogging up from the inside, you’re not alone. Many drivers in Kelowna deal with excessive condensation, especially during cooler or wet months. At the same time, it might seem like a normal seasonal thing, but constant interior moisture can be a sign that something isn’t quite right. At Paragon Motors in Kelowna, BC, we often hear drivers ask why their car feels damp or why the windshield keeps fogging, no matter what they do. The good news is, there’s usually a clear reason behind it.
Moisture Inside the Vehicle Adds Up Fast
One of the most common causes of interior condensation is excess moisture trapped inside the car. Wet boots, jackets, umbrellas, and even snow melting off the floor mats can raise humidity levels quickly. Over time, that moisture has nowhere to go and ends up fogging the windows. Short drives can make this worse since the cabin doesn’t get enough time to warm up and dry out. While this type of condensation is common, it shouldn’t be constant or extreme.
Heating and Defrost System Issues
Your heating and defrost system plays a big role in keeping windows clear. If it’s not working correctly, moisture won’t be removed from the air as it should. A weak heater, poor airflow, or a malfunctioning defrost can all lead to foggy windows that won’t clear. In some cases, a clogged cabin air filter can restrict airflow and trap moisture inside the vehicle. These issues don’t just affect comfort. They can also impact visibility and safety while driving.
Water Leaks You Can’t See
Another cause of excessive condensation is water leaking into the vehicle. This can happen due to worn door seals, damaged window seals, or a blocked sunroof drain. Sometimes the leak is small and hard to notice, but it can still allow moisture to build up inside over time. You might notice damp carpets, a musty smell, or windows fogging up quickly after starting the car. Left alone, hidden moisture can lead to mold and interior damage.
Cooling System Problems Can Play a Role
In some cases, condensation inside the car can be linked to the cooling system. A leaking heater core can release moisture into the cabin and often emits a sweet smell or leaves a greasy film on the windshield. This is a more serious issue and should be checked as soon as possible, since it can affect both visibility and engine performance.
