Hi guys! Please give me your thoughts about my left rear door problem. The door lock is not going up when the remote door opener was pressed, so i have to manually open it through the driver's door, but since I normally use my car myself most of the time, it is not that annoying. It works only if I locked the car, what is usually the problem? Do I need to replace a part, What is that part? Or something was just disconnected? Thanks!
