Is it a problem if the car windows are left open during heavy rain?

When the car windows are left open during heavy rain, water can easily enter the car, which may cause system short circuits. Related information: 1. Precautions: If only a small amount of water enters, it indicates minimal impact. However, for safety, it's best not to turn on any electronic devices inside the car, such as lights or starting the engine, to prevent short circuits caused by water exposure. You can use the key to open the car door, and if it's still raining, cover the car with an umbrella or waterproof cloth. 2. Additional tips: Wet seats may develop mold. Avoid using a hot air blower to dry them; if the seats have a heating function, you can use it to speed up evaporation. After air-drying, apply a leather polish cleaner. For sponge seats, you can remove the entire seat and air-dry the sponge inside.
This situation is definitely problematic because when it rains with the windows open, rainwater can directly pour into the car, causing a lot of trouble. First, the interior can easily get soaked and damaged. For example, wet seats and carpets can develop mold, producing unpleasant odors, and over time, you may need to spend money on replacements, which can be costly. Second, the electrical system might be affected. Rainwater splashing onto the dashboard or electronic components can easily cause short circuits or corrosion, even leading to issues like the car not starting. I must remind you that rainwater also contains dust and pollutants, and if not cleaned promptly, it can increase humidity inside the car, affecting air quality and making it feel sticky when you sit inside. It's best to address this immediately—close the windows properly after parking, and use a cloth to dry any accumulated water. If the interior is already soaked, find a sunny day to air it out with the doors open or take it to a repair shop for professional dehumidification to prevent more serious issues from arising.
I do believe there are risks, especially the greatest harm to the electronic devices inside the car. Rainwater rushing into the vehicle can seep near control modules or sensors, potentially causing signal malfunctions, such as errors in the airbag system, which could be dangerous. Additionally, for the interior, seats and door panels are prone to deformation or discoloration when wet, making restoration time-consuming and labor-intensive. I'd also like to mention that if rainwater accumulates on the floor, it can flow through gaps to the chassis, accelerating the rusting process; this would require subsequent sanding and repainting, adding another expense. It's advisable to develop the habit of checking all windows to ensure they are tightly closed before parking, or keeping an absorbent mat in the car for emergencies. In short, addressing such issues early can prevent small problems from turning into major troubles later on.
