Receiving door ajar indication on 2003 Lincoln Navigator

The door ajar indicator is constantly on, but no door is open. The cabin lights also remain on. All fuses were checked satisfactorily. Could it be the switch /relay for the doors, and if so how do you check them in a 2003 Lincoln Navigator.

    Door ajar light keeps coming on....lights in the cabin stay on after leaving car and securing locks...while driving interior lights flash on and off...bells sounding...spooky ghost type stuff.

    More likely the switch is not making 
    mechanical contact with the door. Can you see the switcvh when you open the door. If so can you make the light go out by pressing int in by hand? Ajust or replace switch if so.

Sounds like you have a Faulty Door Switch. When you open the door there is a Small Button on the Side closest to the Inside of the Truck. Push this in with your Finger and see if they don't go off. Some of these are Movable so you can adjust them in and out.

Try spraying WD40 directly into the door latches and opening and closing the doors several times. Usually this will free a sticking door ajar switch.

The door ajar light remains on which keeps my interior lights on in my 99 lincoln town car

Making an assumption that the TC and the F150 use the same door latch warning indicator.

If this is the case, spraying the door latch with WD-40 really well should cure the problem. Spray the latch, open and close the door a few times, and spray again.

The switch is part of the door latch on the F150, and this is the input sent to the warning system.

Clicking coming from rear right panel in 2003 Lincoln Navigator.

it sounds like you have a door ajar switch issue if it says "door open" when it's not. Is it clicking in the passenger rear door or in the storage area behind the rear seat behind the right trim panel?
The liftgate wiring may be back there.
Your door lock & unlock relays are in the vehicle security module which is under the center area of instrument panel.
I looked at the wirng diagram and don't see too much back there.
Let me know what you find on where the clicking is coming from.
We'll go from there

2003 Explorer door ajar light stay on when all doors are closed

I had this problem on my 2003 explorer and took WD40 and gave the lock mechanism a good dose where it meets the clasp on the door jam. Then open and close the doors a couple of times to get them working. They get gummed up and sometimes have a tendency to stick.

Door ajar light stays on

I have the same problem with my passenger door all the time. The dealer was nice and didn't charge me for some advice. Find out which door it is or do this to all. It is the part on the door the grabs the round thing in the door jam. It looks like two fingers kinda. Spray with WD-40 and clean with a rag to get all the dirt out of there. Spray again and open and close the door several times. This clears my problem and I hope this helps you too.
