If the vehicle has been submerged in water for a short time and the damage is not severe, simply remove the water from the interior and dry all items inside. Check the electrical circuits; if they are functioning normally, the vehicle can be started as usual. If the vehicle has suffered severe water damage, it is necessary to file an insurance claim. The insurance company will assess the damage before the vehicle is sent to a repair shop for restoration.

Minor flood-damaged car repairs, I've been through this many times. Step one is to quickly drain the water—use a vacuum or towels to remove floor water, preventing it from seeping into electronic modules. Next, remove seats and carpets for thorough cleaning, disinfection, and stain removal, then air-dry or use fans for over 24 hours. Check all wiring connectors and fuse boxes—if wet, unplug and dry them to avoid short circuits. Finally, reinstall and test lights, audio, and AC functions. Don’t forget to inspect brake sensors, as residual moisture can affect performance. The entire process should ideally be done in a shaded area—avoid high-heat tools to speed up drying, as they may damage plastic parts. After completion, drive for a week to check for lingering odors or abnormal noises.

My car was previously soaked in heavy rain, with the water level only reaching the floor mats. I immediately removed the carpets, used towels to absorb all the water, and then cleaned and disinfected the area under the seats. I left the fans running all night to dry out the interior and prevent mold. The next day, I checked the wiring harnesses and computer modules under the car to ensure there was no rust or moisture. Before starting the car, I tested all functions to confirm they were working properly. Remember to act promptly, otherwise, it can corrode metal parts and wiring harnesses, leading to more expensive repairs later. I recommend spraying some deodorant after repairs to completely eliminate any hidden risks.

For repairing slightly water-damaged vehicles, I recommend focusing on drainage and electronic inspections. First, drain any accumulated water from the chassis, then use a dehumidifier to dry the interior for several hours. The critical step is to check the drying status of wiring connectors and modules, as any moisture can cause system failures. Find a reliable repair shop to thoroughly test core components like the AC and ECU. Avoid DIY repairs for insurance claim items to keep costs lower.
