Principles of Operation
Interior Lighting
The interior lighting is broken down into two groups: the courtesy lamps and the illuminated entry lamps. Both lighting features interact with the courtesy light arbitrator. The battery saver is also listed in this section.
Courtesy Lighting
The courtesy lamps consist of the dome lamp and/or map lights. The courtesy lamps can be activated by the GEM using the panel dimmer switch, or by any ajar door. 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 8 kph (5 mph). The interior lamps will not be reactivated until the vehicle speed is less than 5 kph (3 mph) and a new door open warning lamp switch signal is received. The inputs are:
Interior lights and the power door locks are controlled by a electronic control module . Hooking up a factory or some other type professional scan tool an checking for codes an viewing input data to these control modules would be the first thing to do.
The interior lighting system consists of the following:
lighting control module (LCM)
driver door module (DDM)
instrument panel
dome/map combination
courtesy/reading lamps
orientation light
door lamps
footwell lamps
luggage compartment lamp
glove compartment lamp
vanity mirrors
door ajar switches
viewing wiring diagrams an checking power and ground circuits for these modules would be the next step if no codes were found . Principles of Operation
Lighting Control Module
This vehicle uses a lighting control module (LCM). The LCM is a microprocessor-based module that controls several vehicle subsystems, responds to electrical input signals from various switches, sensors, and external modules and is located on the LH side of the instrument panel. LCM subsystem functions include:
headlamps with autolamps
turn signal lamps/hazard flasher lamps
cornering lamps
parking lamps
daytime running lamps
interior lamps
demand lamps
battery saver
The LCM interfaces with the driver door module (DDM) via the standard corporate protocol (SCP) network for the illuminated entry feature.
The interior lamp is illuminated by pressing the individual interior lamp switch. The interior lamp is also illuminated by door ajar switches located in the door latches, when any door is opened. A theater lighting feature gradually increases or decreases the light intensity when switched by opening or closing a door.
The dome/map lamp combination are located on each side of the interior lamp. The map lamps are operated independently of the interior lamp by two switches located on the interior lamps.
The interior lamps are illuminated by holding the panel dim switch in the UP position until the dome lamps turn on. The interior lamp also illuminates when a door is opened and actuates the door ajar warning lamp switch in the door latch.
The front map lamps are powered by the demand lighting circuit and the interior lighting circuit.
The rear passenger reading lamps are incorporated into the rear seat assist handle and are located over the rear door openings. These lamps are illuminated through power supplied by the LCM demand lighting circuit.
Interior lamps (controlled by the LCM) are activated by using the dome lamp switch (instant ON/OFF response) or when a door is ajar. The following lamps illuminate for interior lighting:
instrument panel interior lamps
front map lamps
rear reading lamps
door lamps
Demand lighting includes lamps that are illuminated by the customer by directly actuating a switch. The front dome/map lamps are located in the overhead console. Each lamp is controlled by its own switch.
The following demand lamps are powered by the demand lighting output of the LCM:
glove compartment lamp
vanity mirror lamp
luggage compartment lamp
Each lamp has a dedicated switch that closes to ground to illuminate the lamp.
The front map lamps are powered by either the demand lighting circuit or the interior lighting circuit, depending upon the position of the switch associated with each lamp. When the customer turns the front map lamp switch ON, the front map lamp is illuminated through power supplied by the LCM demand lighting circuit. If the customer moves the map lamp switch to the OFF position, the power from the LCM demand lighting circuit is interrupted and the lamp is reconnected to the interior lighting circuit.
The rear reading lamps are powered by either the interior lighting circuit or the demand lighting circuit.
The luggage compartment lamp is controlled by the trunk ajar switch, and is powered by the demand lighting output from the LCM, and is mounted near the center of the upper rear panel.
The glove compartment lamp system consists of a glove compartment lamp switch and wire and miniature bulb assembly. Opening the glove compartment door closes the switch which provides power to the glove compartment lamp switch and wire. The glove compartment lamp switch is grounded to the body sheet metal.
The vanity mirror lamp system consists of a switch and bulb assembly in the RH inside visor and the LH inside visor. Lifting the vanity mirror cover closes the vanity mirror lamp switch and provides power to the lamps.
The illuminated entry system is controlled by the LCM and provides interior lighting upon entry to the vehicle.
Interior lamps will be illuminated for 25 (±1) seconds which includes a theater lighting ramp-up time (0.5 seconds). This time interval does not include the theater lighting ramp-down time. Interior lamps will be turned off before the 25 (±1)-second timeout if the ignition switch is turned to the RUN or ACC position.
The illuminated entry system has the following additions to accommodate the remote entry system: pressing the unlock button on the remote transmitter will activate the illuminated entry system (with theater ramp-up). When the driver door module detects a button press, it sends a signal on the J1850 communication network activating the interior lamps. The lighting control module will turn off the lamps by sensing the all doors lock signal.
The battery saver feature prevents excessive drain from loads inadvertently left on. When the ignition switch is turned OFF, power is interrupted to the interior lamps and headlamps (after a 10-minute timeout) and the demand lamps (after a 30-minute timeout).
The battery saver has the following inputs:
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 .

Might try closing all doors, then open one at a time and manually depress the switches. Feel them for "click" feeling and see if by depressing fully you can make the light go out. Remember also that you have a switch which turns the lights to on even with all doors closed. And also, the driver's door sees the most use so that switch is the most likely to fail, plus those hinges wear causing the door to not close as well.
the door light switch, little black thing that sticks out on the door hinge side, this may need replacing. some times they have a rubber on them, its a switch.
If only the door ajar light and interior light is not working it is probably the door ajar switch located on the door latch inside the door. sometimes a little WD40 sprayed towards lower side of the latch will work, frees the piston in the switch. if not the switch must be replaced. If also the outside mirror control does not work, the door lock switch also does not work, it is a bad ground to those three systems, the Electric windows have a separate ground wire and still work. You must feed a new black wire from a good ground on the body thru the door accordion tube and connect it to the larger black wire on the plug that goes to the door lock switch. The door lock, the mirror control, the door ajar light, and the interior light problem will be gone.
one of your door pins are stuck . they are mounted inside the doors , they are attached to the latch plates. the trick is which one is bad .most times its the drivers side but not always.
good luck chris

the door switch needs to be replaced or adjusted. Or the door is not closing tight enough
All doors are closed and the door ajar dashboard indicator and interior light are on
