If you are not an auto techie kind of person, I fixed this problem on my 2007 Saturn Relay by first: pushing the switch on the overhead center console panel to operate the rear doors in manual mode rather than automatic; 2) opened the rear plastic panel that conceals the tire jack; 3) unplugged the top grey plug that is located right in front of the jack (controls the automatic door, including the alarm). That was to stop the infernal dinging because apparently the sensor of the automatic door on the passenger side is bad. It works perfectly now in manual mode, and no dinging.
