I own a 2007 model 407 with the Executive package. Last week, when I opened the car to go to work, the left front door wouldn't unlock from the outside. Then I unlocked it from the inside, and I haven't had these problems again until yesterday. However, yesterday, when I locked the car, I noticed that the left front door wouldn't lock. The door doesn't lock with the key or the remote control. Also, when the door is open, there's no door open warning on the trip computer. As you know, a car normally doesn't lock when any door is open, but when I press the lock button on the remote control while my left front door is open, all doors except the left front door are locked. In short, the car doesn't detect the left front door at all. I also noticed something today: The driver's seat belt warning doesn't work either. What could be the cause of these problems? I need your help.
