back lift door/window ajar alert light on. Checked all. Can't get it to turn off

Hello, a diagnostic tool can show what doors or the lift gate window is seen as being open -- even when they are all shut. When this is found, you drill down to the door ajar switch located at each opening and see if it is working as designed. Latches and switches can sometimes be lubricated to resolve this, but only hands on testing and checking of the components is helpful.
