Does Water Entering Through the Door Glass Gap Have Any Impact?

[LaJoseph]

Water entering through the door glass gap can have significant effects on the vehicle. Here are the specific details: 1. Severe Water Ingress: The electronic modules inside the vehicle can be soaked in water. If not handled promptly and properly, it can corrode wires, connectors, and internal circuit boards, leading to vehicle alarms and functional failures. In such cases, avoid turning on electronic devices if possible. Use a mechanical key to open the door and call for a tow truck to send the vehicle to a repair facility immediately. 2. Minor Water Ingress: If there isn't a large amount of water accumulation on the floor mats, it is recommended to remove the vehicle's battery to prevent electrochemical corrosion, which could worsen the rusting of modules and connectors. Then, take out the floor mats and seat covers for cleaning and drying to prevent odors later on.
