Why Can't the Car Door Open on Rainy Days?

[MacColton]

On rainy days, the inability to open the car door may be caused by moisture affecting the central locking system's wiring. Below is relevant information about the central locking system: 1. Introduction: The central locking system, fully known as the Central Control Door Lock, is a car accessory that allows remote locking and unlocking without inserting the key into the lock. It consists of a door lock switch, an actuator, and a controller. 2. Main Functions: When the driver locks their door, all other doors lock simultaneously. The driver can unlock all doors at once using the door lock switch or open a single door individually. When the vehicle reaches a certain speed, all doors automatically lock to prevent accidental opening by passengers. Besides the driver's door, other doors are equipped with separate spring lock switches for independent control of each door.
