What to Do If the Passenger Window Was Left Open During Rain and Water Got Inside the Car?

Methods to handle water ingress in the passenger side are as follows: 1. Minor splashing or water ingress: Remove the wet floor mats, carpets, and seat covers, clean them with automotive-specific detergent, and let them dry. Then, extract any standing water in the car, clean the area again, and let it dry. Check nearby electronic devices for any moisture exposure; if found, dry them thoroughly before testing. 2. Severe water ingress: First, remove the floor mats and floor coverings, then locate the sealing plugs at the bottom of the car's chassis and open them to drain the accumulated water. Clean the floor mats, seat covers, and other interior components as described above. If the seat foam has absorbed water, remove the seats for drying to prevent long-term rotting. After the car has dried, inspect the wiring system and electronic devices for any damage and replace components as necessary.
I've encountered this situation several times. When it rains and the passenger window is left open, water pours into the car and needs to be dealt with immediately. First, find a safe place to park, close all windows to prevent more water from entering. Use a towel or thick cloth to absorb the moisture on the seats to avoid damaging the material. Open the car doors to ventilate and allow air circulation, then start the engine and use the air conditioning in warm air mode to dry the wet areas. Be careful not to touch the car's electrical circuits to prevent short circuits. Check if the floor mats are soaked; if they are, remove them to dry, otherwise they can easily mold and affect health. After handling, let the car air dry for at least a day before driving to prevent lingering odors and ensure driving safety.
Don't panic if you find water entering through an open window. Immediately close the window, park the car, and absorb the moisture. Thoroughly wipe the seats and floor with a towel. If the carpets are wet, remove them to dry in the sun or use a vacuum cleaner. Open all doors to improve ventilation and use the warm air from the AC for half an hour to speed up drying. Check for any musty smell after a couple of days and clean it to prevent interior contamination. Significant water ingress may damage electronic components, so inspect the wiring and fuses for proper function. Make it a habit to check your windows when parking to avoid such troubles and save on repair costs.
