Lock issue

I am driving a 2010 model [peugeot partner 1.6hdi adventure]. The lock on the right front door of the vehicle sometimes opens after the vehicle is locked, and sometimes it does not. Once the central lock is unlocked, it remains locked again. When I open it manually or unlock it with the key, the central lock continues to open and close the lock on the right-hand door this time. This problem seems to be resolved in this way. But when I open the car with the remote after 1 day or a few hours, the right front door lock remains closed again. When it unlocks manually, the central lock continues to open and close the door as if there was no problem. What do you think could be the problem? I would appreciate if you help ...

I think there may be a lack of contact with the connection cables to the lock rather than the lock failure. If the lock was broken, it should not continue to operate as if there were no problems after opening the door with the hand or key. But in this way, after opening the door, it continues to work smoothly in every opening and closing. This vicious circle continues when you don't use the lock for a while. Even when the lock (right front door) is not working, even if I press the open-close button, there is not the slightest movement in the lock or the smallest sound that it opens and closes. The other doors open and close quite loudly. It seems likely that the cables leading to the lock have been cut. Just guess ... Do you think there is such a possibility?
