Why Are My Car Windows Fogging Up Inside When Parked?

When a car is parked and not in use, there is minimal airflow passing over the windows. This lack of airflow can cause the moisture on the window surface to condense into tiny droplets, resulting in fogged windows.

To prevent fogging of car windows when parked, there are a few measures you can take. Firstly, you can crack the windows slightly to allow outside air to circulate inside the cabin, reducing the condensation. Secondly, parking your vehicle in a garage when it is raining can minimize the exposure to moisture and prevent fogging. Lastly, turning off the car heater can help minimize moisture buildup inside the car and reduce the chances of foggy windows.

Could a damaged or faulty window seal be causing the interior fogging?

If you notice that your windows are consistently fogging up, it is possible that there is a damaged or broken seal on the window. This issue can result in water damage, the growth of mold, and stains on the floor. It is advisable to address this problem promptly to prevent further complications.

The most frequent indication of a broken window seal is the presence of visible condensation. When a window seal becomes faulty, moist air can infiltrate the space between the panes, leading to the fog that you are observing. Without taking any action, the fog may either decrease or worsen over time.
