Hi all! I need help here on my driver side door. The symptom is my driver side door cannot be opened from outside, the handle just pops out and stays at 'pull out' position. However, the central locking and the inner door handle work without any problem, I can open the driver side door from inside only now. What should I do to solve this problem?
