why does the door ajar light keep comming on and alarm going off sometimes on 1997 Infiniti QX4

all doors are closed and light comes on when driving and you cant lock doors. sometimes in the midd le of night the alarm will go off or rear dome light will be on

The most likely problem will be a door switch failing or out of adjustment. As the car "flexes" going down the road the switch will move in and out of position. As it cools during the evening the same effect comes into play. If you like call me at 772-462-0061 and we can set an appointment for you.
