I have a 2005 Saturn Relay. Was having the same problem. Door would randomly open or stick open with chime driving me crazy. Finally a complete failure happened and the door refused to stay closed. Turns out that the electrical assembly with 7 pins had completely fallen apart inside the door. The part #12457713. GM was selling online for $50. Now has a new part # and is sold only as a kit for $188. I was able to home repair the existing for $4 in parts from local hardware store. This part is very poorly made and prone to failure. This is scary, considering this is were we are told our children are safest in the vehicle.
