Your domelight has a 3 position switch on it. Always off, always on, and on when the door is open. Check this first with the doors closed. If it stays on in every position, this is a problem with the switch, or a short in your wiring. Each door has a button that is depressed when the door is closed. Go to each door one at a time and depress the switch several times to see if the light will go out. The most common problem is the mounting for the switch is loose and it won't allow the switch to go in all the way. If you still have a problem you will need to disconnect each switch until you find the short or find the connector under the dash and troubleshoot it.
The door ajar sensor, on a 2005 Ford escape, is located inside the door panel behind the door lock. There is a sensor on each door.
I had the same problem with my 98 Ford Expedition XLT. I sprayed WD-40 on all the door jams including the hatch. It fix problem been 3 years now.
Door Ajar.

Is door ajar light on also?
check the sensor on the door, its probably bad
If your interior light is also on, replace the door switch.

Try spraying WD-40 on the door latch, the part that is on the door itself. The door ajar switch is located in with the latch. Had the same problem, door ajar light on, interior light stays on, and horns toots twice when you lock with remote, to signal door is not closed. Door was shut but truck didn't know it, WD40 fixed it.
On my 2002 sportage 2-door, the door ajar light stays on when the tailgate is not locked. with the key.
The door ajar switch on the 2008 Ford Sport is located inside the door that is mounted on the backside.
