I have a 2005 buick terezza with the same problems. Taking the fuses out fixed the dinging and door opening by itself. About 2 months later my door sttopped opening manually. My fiance let someone help her try to open it and he broke the handle. That was about a year ago. I finally got around to ordering the new handle, But I can't get the door to open now manually or electronically. It will open a little bit, seems to come completly unlocked but will now slide back. Any help would be appreciated
