Is it okay if the co-pilot window was left open and got rained on?

[DelCarlos]

Whether leaving the co-pilot window open and getting rained on has any impact depends on the extent of water ingress. Below are specific explanations for different water ingress situations: 1. Minor water ingress: If only a small amount of rainwater has drifted in, it will not affect the car's wiring system or mechanical system, as the wiring system is protected by covers. Simply clean and dry the wet items. 2. Severe water ingress: Rainwater may enter the cabin, potentially causing malfunctions in electronic devices or rusting some components inside the cabin. Additionally, since the co-pilot seat is close to the central console, rainwater is likely to wet electronic devices when entering the car. Even if the electronic devices are not damaged, the co-pilot seat, floor mats, and other interior parts may still get soaked.
