I have a 2002 Ford Explorer. For some time the door ajar warning light and the alarm sound would come on intermittently, even though the doors were all shut. This usually started after making a turn or hitting a bump. The problem occurred during a diagnostic test drive with the dealer's technician. His computer indicated a problem with the rear hatch. The technician said he would have to replace both sensors in the rear hatch and its window, since he could not tell which one was faulty. I replaced both sensors, and now the door ajar light stays on continually but thankfully the alarm sound has not gone off. However, the door ajar light will go off if the rear hatch or its window are open!
I can live with the door ajar light staying on as long as the alarm does not go off. Any ideas?
Follow-up: I used an ohm meter to test the two sensors I removed. They behave exactly opposite. The one shows a closed circuit until the button is pressed in. The other shows an open circuit until the button is pressed in. I presume they both can't be correct, since they are supposed to detect an unlatched door. So replacing one of them was necessary. But it still does not explain why, with the new ones in place, the door ajar light goes off only when the window on the hatch is open.
