Door Ajar Lite Stays On

family, The only way you can tell for sure is by hooking up a diagnostic tool that can access the different components and check. One of the doors that says "OPEN" will actually be closed. The only way you can do anything else it to perhaps try to lubricate each latch on each door, and then open and close them several times. The door ajar switches are located on the latches themselves and sometimes bind. Lubing and working the lube in can sometimes free them up. Good luck.
