Will leaving car windows open during rain affect the vehicle?

[StElizabeth]

If the car windows are left open during light rain, there is generally no significant impact. However, heavy rain may lead to water accumulation inside the vehicle. Small amounts of rainwater entering the cabin or even larger-scale water ingress will not damage the car's internal wiring system or affect its mechanical components. This is because the vehicle's electrical circuits are protected by sheathed wiring, making them less prone to issues. If you notice abnormal headlights or other functional irregularities while driving, it is advisable to have them inspected and repaired promptly. Below is a detailed breakdown of the necessary steps: Cleaning carpets or floor mats: If rainwater has seeped into the carpets or floor mats, they should be removed, cleaned, and dried. Disinfection: After addressing the water accumulation, it is essential to disinfect the interior to prevent lingering odors. Removing seats due to mold: If there is water on the car floor, or if it has seeped beneath the floor covering, or if a musty smell persists after drying, it indicates that the area beneath the floor mat, including the padding, has become damp and moldy. In such cases, professional repair services are required to remove the seats and lift the floor covering for thorough cleaning to eliminate the odor.
