Does leaving the car window open in the rain affect the vehicle?

[LukeMarie]

Generally speaking, a small amount of rainwater entering the car or even a large-scale water intrusion will not damage the internal wiring system of the vehicle, nor will it affect the mechanical system. Here is relevant information: 1. Reason: Because the car's electrical system is protected by sheathed wires, problems are unlikely to occur easily. If abnormal headlights or other functional abnormalities are noticed while driving, it is advisable to have them inspected and repaired promptly. 2. Treatment method: If the electrical equipment is not affected, simply going to a 4S shop for a drying treatment is sufficient, and generally, the issue is not serious. If rainwater has seeped into the carpets or floor mats, they should be taken out, cleaned, and dried. After addressing the water accumulation issue, it's also necessary to sterilize and disinfect the interior of the car to prevent lingering odors.
