Does it matter if it rains with the car window slightly open?

Leaving a small gap in the car window during rain is generally not a problem if only a little water gets in; however, if a significant amount of water enters, it can potentially cause electrical short circuits. Here are some safe ways to use car windows: 1. Opening a single window: To dissipate odors (like smoke): The main purpose of opening a single window is to remove unpleasant air from the car. When smoking, opening a side window allows the secondhand smoke to exit quickly. While some smoke might escape elsewhere, this method is the most effective. Cracking the window slightly helps dissipate fog faster without blowing air onto passengers in the back. 2. Closing the front window on one side (quick odor removal): This means closing the window next to the driver and opening the other three windows. This creates an unbalanced airflow with a clear directional flow, allowing odors inside the car to be expelled quickly. 3. Never open windows on the same side while driving at high speeds (dangerous): When driving on the highway, either keep all windows closed or open just one window. Avoid opening two windows on the same side simultaneously, as this can cause strong airflow to rush into the car from one side.
