How do i close back windows

courtesy light switch , is door ajar switch an it's part of the door lock actuator . Light on coming on ? Not going off ? The ajar switch is a input to the GEM module , fords BCM - body control module . The GEM will energize a relay to turn on the lights .
The GEM will illuminate the interior lamps when any door is open or ajar. The interior lamps are; the dome lamp, the rear cargo lamp, the door courtesy lamp and the side rail lamps. The courtesy lamps will shut off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 5 mph (8 km/h). The interior lamps will not be reactivated until the vehicle speed is less than 3 mph (5 km/h) and a new door open warning lamp switch is received.
The GEM controls the interior lamps illuminated entry function by activating the interior lamp relay.
Mite be a good idea to have it check for DTC'S - diagnostic trouble codes .

L4 CHECK THE VDM FOR DOOR AJAR INPUT

• Key in ON position.
• Monitor VDM door position status PID.
• Close all doors, liftgate, liftgate glass and power running boards.
• While observing the diagnostic tool, open and close one door.
• Does the door status PID change between CLOSED and AJAR states?

When you open an close the driver door you have no PID change ,right ?

The door ajar input is an input to the Vehicle Security Module , then transmitted over the bus ! You'll have to find a diagram for the med. speed CAN data bus .

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.

try rolling down a window or leaving a door open, shut liftgate hard. see if it still shows liftgate ajar. on my explorer the seals in door and windows shut so tightly that it was almost impossible to get the gate closed completely with doors closed and windows up.

if this doesn't help then you might need a new switch on it.

THE ACTUATOR IS BROKEN FOR REAR DOOR AND THE DOOR AJAR LIGHT IS ONE OF THE BUTTONS LOCATED IN THE DOOR JAM MALFUNCTIONING

Check with the dealer. For a short while there was a recall on the rear window liftgate.

If you are talking about the entire metal back door, thats a bigger problem.

Either way, your 2006 Lincoln has a long warranty and may be covered.

Find out which door is showing ajar and replace the latch or door ajar switch.

There should be a switch in the door frame which the door pushes in when it is closed. Sounds like it's loose or pushed back into the frame.

replace the lift gate/door ajar switches, they are located inside the tail gate on the left and right latch assemblies.

be sure to close window above liftgate completely until it clicks
