Does leaving a small gap in the car window matter if it rains?

Leaving a small gap in the car window with a little rain getting in is not a big issue; however, if a significant amount of rainwater enters, it may cause short circuits in some wiring. Safe ways to use car windows are as follows: 1. Opening a single side window: To dissipate gases (like smoke): The main purpose of opening a single side window is to release unpleasant air from inside the car. When smoking, opening the side window quickly expels secondhand smoke, though it may disperse elsewhere, this method is the most effective. Opening the window slightly allows fumes to dissipate faster without blowing directly at passengers in the back. 2. Closing a single front window (for quick odor removal): This means closing the window next to the driver and opening the other three windows. This creates a highly unbalanced air flow with a clear directional movement, allowing odors inside the car to be expelled quickly. 3. Never open windows on the same side at high speeds (dangerous): When driving on the highway, either keep the windows closed or open only one window. Avoid opening two windows on the same side simultaneously, as this causes airflow to rush directly into the car from one side.
I had a similar experience. One day I forgot to close the window tightly, leaving a small gap, and it rained. The rainwater dripped in through the gap, completely soaking the seats. I was in a hurry to go to work and didn't notice, but when I got off work, I found the entire car damp and musty. It cost me hundreds to have it professionally cleaned at a car wash. A little breeze is nice on a regular day, but it's a different story when it rains. If too much rainwater accumulates, it can corrode the electronic components inside the car, like causing short circuits in switches or circuits, leading to unnecessary repair costs. I suggest that even if you leave a gap for ventilation on nice days, make sure to close it tightly when the weather forecast predicts rain. Developing this good habit can save you both hassle and money.
I've noticed many car enthusiasts ask about this. Actually, rainwater getting inside the car is really not a good thing. Especially when leaving a slight gap, raindrops not only soak the carpets and seats but also easily cause mold and unpleasant odors. Even worse, if internal components like circuit boards or switch contacts get wet, short circuits can occur, leading to troublesome and costly repairs. But don't panic too much—small amounts of rain might just leave a few droplets that can be wiped away. Personally, I always check around the car when parking to ensure the windows are tightly closed, and I never take risks on rainy days. Prevention is better than repair—saving money to buy some nice accessories is much more enjoyable.
