What is the reason for the co-pilot door of the Emgrand GL not opening?

[MaliaDella]

The co-pilot door of the Emgrand GL not opening is due to a malfunction in the door lock actuator, which requires timely repair or replacement at a 4S shop to avoid affecting normal door opening and closing operations. The function of the car lock actuator: The car lock actuator is a specialized term, essentially referring to the car door lock controller; it is a control device that provides locking/unlocking pulse current to the door lock actuator. The principle of the car lock actuator: Regardless of the type of door lock, they all control the left and right movement of the linkage by changing the direction of the current supplied to the actuator, thereby achieving the locking and unlocking of the door. A worm gear fixed on the motor output shaft meshes with a gear, and the inner cavity of the gear meshes with a swing arm. The working principle is: the vehicle's current source supplies power to the motor, the motor's rotation is converted into the swing of the swing arm, thus completing the opening or closing cycle.
