Where is the central locking control box located in the old Jetta?

[Fritz]

Old Jetta's central locking control box is located under the left side of the dashboard, which is a control unit integrated with the power window system. Below is some information about the central locking control box: 1. Function: It can simultaneously control the opening and closing of all vehicle doors. Once activated, people inside the vehicle cannot open the doors. 2. Features: Central control - when the driver locks their door, all other doors lock simultaneously. The driver can unlock all doors via the door lock switch or open individual doors separately. Speed control - when the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening doors by operating the door handles.
