Have you ever started your car only to realize foggy windows impede your visibility? Many drivers experience humid cabins inside their vehicles without understanding that it can be a sign an air conditioning or auto repair is needed. While many factors can contribute to interior condensation, determining the cause is the best way to eliminate humidity inside your car.

Why Your Car's Interior Feels Damp

When warm, humid air touches a cool surface, condensation develops. That's why you might experience foggy windows when the heat is turned on during cold weather and your vehicle has excess moisture inside its cabin. Water in the air can also gather on the glass when a person's breath hits against a cold windshield, and any moisture inside your vehicle can also freeze on windows in freezing temperatures.

Numerous factors can cause excess moisture inside your car, including wet clothes, hot beverages, and garbage. There could also be mechanical problems contributing to the event. Coolant could leak into your vehicle from a faulty heater matrix, or you could have a leak in the car's vent system, windows, or doors. 

How to Eliminate Excess Moisture

Start by checking your vehicle and removing the source of extra moisture, such as damp gym clothes or trash. Feel around different areas of the carpet and trunk. If the carpet feels moist, you could have a leak in the seal around your windows or doors. 

Similarly, there could be a leak in your air conditioning system. Consider taking your vehicle for an inspection by an auto repair technician. Describe the humidity inside your vehicle and explain the steps you've taken so far to remove it.
