Interior lights keep turning on and off on their own when the car is off?

Also, the light indicator on front panel will not go off when all the doors are closed so the alarm will not set.

Hi,

Each of the doors has a door ajar switch on them which will turn the lights on as you described. By chance, are any of the doors not closing tightly?

Also, if the light on the dash stays lit, that is an indication that the problem is within that circuit. If you press on any of the doors, does the light turn off?

Let me know.

Joe

No, the lights stay on. They do go off like they are supposed to. But comes back on its own.

Hi,

If it turns off and then back on, it does sound like a switch.

Do me a favor. When the light turns on, one at a time, remove the fuses in the central junction box. See pics below.

Let me know if that does turn them off so I know if there is a short to power from a different circuit or if the issue is after the fuse.

Let me know.
