What to do if a little water gets into the car?

When opening the car door, do not use the remote control directly. After water enters the car, avoid any electrical activation. Although cars are generally waterproof, to prevent circuit short circuits, it is essential to check all electronic components. Remove all items from the car, as the carpets are usually quite damp. Use a vacuum cleaner to suck up the water, and ensure the seats are dried thoroughly. Open the car doors and sunroof under the sun to air out the car. The main goal is to ventilate the car, ensuring all water inside is absorbed completely, followed by disinfecting the car.
When a car gets a bit of water inside, as an experienced mechanic who often deals with such issues, I would act immediately to prevent bigger troubles. First, check where the water is coming from—common sources include aging door seals or clogged sunroof drains. Use a dry cloth to wipe away all visible water, especially on the dashboard, center console, and carpet areas. Turn on the AC heating mode at maximum fan speed for at least half an hour to dehumidify and dry out the interior moisture. Don’t rush to start the engine; wait until it’s confirmed dry before testing. Water in the engine bay is even more dangerous—check if the air filter is soaked. Too much water ingress can cause electrical shorts or rust; if electronic devices malfunction, take it to a professional shop for a full inspection. For prevention, regularly clean the drainage pipes and replace worn seals.
