On Tuesday my driver side door all of a sudden would not open. I pulled the panel off and when I press unlock it appears to be operating and moving the lock up to an unlocked position. The door will not open though. On Saturday when I tried different methods of locking and unlocking all of a sudden the back door on the driver's side wont open either. Any idea what is going on with my car? My main concern is the driver's door. I don't want to keep climbing across to get out of the car. Thanks.
