If the car window is left open during rain and water gets inside, it can cause problems, such as short circuits and damage to electrical equipment. Below is some relevant information about car windows: 1. Window Frame: Aging window frame seals can create noise during window operation, cause the window to move unevenly, and even lead to malfunction. Over time, this can result in motor overheating and burnout, damage to the window lift mechanism, deformation of the glass bracket, and other issues. If these symptoms occur, check the condition of the window seals. If they are aged, replace them promptly. 2. Benefits of Car Window Tinting: (1) Heat and UV Protection. Tinting can effectively block a significant amount of heat from infrared rays. For example, Mocha’s front windshield film MA70 can block up to 99% of infrared rays. (2) Enhanced Privacy. After tinting, the interior becomes difficult to see from a distance of one meter, ensuring privacy and safety.

Leaving the car window open during rain will definitely cause problems. I once helped a friend deal with a similar situation—rainwater entering the car can soak the carpets and seats. If not dried promptly, mold can grow within a day or two, producing an unpleasant odor. More dangerously, it may corrode the vehicle's electrical wiring, such as the modules controlling the air conditioning or audio system. If a short circuit occurs, it could lead to electrical malfunctions or even fire hazards. For cars with sunroofs, water may seep into the headliner, causing more severe internal damage. If you discover water ingress, immediately use towels to absorb the moisture, turn on the air conditioning to dehumidify, or open all windows on sunny days for ventilation. During humid weather, it's especially important to check the window seals to prevent such risks.

Is it normal for the car interior to be damp on rainy days?

It is normal for the car interior to be damp on rainy days. Here are some related introductions about cars on rainy days: Precautions: Be cautious when driving on roads with accumulated water, generally moving forward at low speed in a straight line, and avoid stopping arbitrarily. If the water level exceeds the exhaust pipe, detour is necessary. Cleaning method: If you find that the wiper blades have hardened during cleaning, replace them immediately. Because hardened wiper blades cannot fully adhere to the glass, they fail to clean the glass effectively. After cleaning the front windshield, if dirt is not removed promptly, an oil film will quickly reappear, and it will accumulate thicker over time.
