The door switches are built in the latches on each of the doors, they are pron to sticking, leaving the security module to beleive the door is open.
The simple fix is to spray a generous amount of WD40 on, in, and around the door latches, then opening and closing the door a few times. I would start with the passenger door as`this is likely the culprit. do the rest of the latches as a prevenitive measure.
Hope this is of some help.

Fix door ajar first. One of you door or liftgate switches is not closing all the way probably.
This may fix running board nut retracting, because it needs to know door is closed to fully retract. It is an unput to the running board module.
You have about 5 modules receiving input to operate the running boards.
The mirror not going down when backing up is a common problem. It was deleted in production for that reason. I would not bother with fixing it.
2003 was a new model. I have worked with the mirror team on issues with that mirror.
The feature I was referring to, is the feature that moves the mirrors down when the vehcile is in reverse. It's to help see if anyone is near vehicle, like on a tricycle. Either they stayed down or they would not go down. That was the feature we deleted.
You seem to be saying it is always oriented up. Do you have memory mirrors?

SECTION 501-09: Rear View Mirrors
2003 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION
Rear View Mirrors
The rear view mirror components consist of: the interior mirror.
the auto dimming mirror (optional).
the exterior power folding mirror (optional).
the exterior mirror.
the exterior mirror control switch.
the memory set switch.
The interior mirror: is windshield mounted.
is a manual hand-set day/night or an optional auto dimming interior mirror.
The auto dimming interior mirror has two features: automatic dimming
normal view state automatic lock-in when the vehicle is placed in R (reverse)
The automatic dimming feature darkens the interior mirror whenever the front ambient light sensor detects low outside light and glare reaches the light sensor (photo cell), which is located inside the interior mirror. The auto dimming interior mirror starts to return to the normal view once the glare goes away.
The exterior mirrors: are controlled by power controls on the LH front door trim panel.
are of a foldaway design.
may contain turn signal indicators.
may be heated when the heated back window glass is activated.
may have a programmable recall memory option.
Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
The DSM system consists of the following components: driver seat module (DSM)
driver memory seat switch
memory mirror switch
memory set switch
front vertical seat motor
rear vertical seat motor
driver horizontal seat motor
LH heated memory mirror
RH heated memory mirror
The DSM incorporates multiple functions into one module and offers diagnostics to easily locate and repair concerns affecting the subsystems that it controls.
Power Exterior Mirror Operation
The power exterior mirrors are controlled by the DSM and are operational all the time, whether the ignition switch is on or off. Using the power exterior mirror switch, the driver can adjust the driver and passenger exterior mirrors four ways.
Up/Down Motion
The power exterior mirrors can be moved up and down under motor control by actuating the power mirrors UP/DOWN switch. The DSM will power the driver or passenger mirror up/down motor until the switch is released or until the travel limit is reached.
Left/Right Motion
The power exterior mirrors can be moved left and right under motor control by actuating the power mirrors LEFT/RIGHT switch. The DSM will power the driver or passenger mirror left/right motor until the switch is released or until the travel limit is reached.
Mirror Selection — Driver/Passenger
The driver can select the driver or passenger mirror to be adjusted by setting the mirror select switch to the appropriate position.
Turn Signal Mirror
The exterior mirror may be equipped with a mirror-mounted turn signal assembly. For Diagnosis and Testing, refer to Section 417-01 .
Power Folding Mirrors
The power folding exterior mirrors are controlled by the power folding mirror switch. The power folding mirror switch has power at all times.
Memory Power Exterior Rear View Mirror Operation
The memory power exterior mirrors feature allows the driver to program personalized mirror positions that can be recalled using the memory switches or remote transmitter. There are three memory settings possible. The power driver seat positions are also stored, and recalled with the memory exterior mirrors positions

If the vehicle is equipped with memory exterior mirrors and the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel. Select the vehicle to be tested from the diagnostic tool menu.
Check to make sure the program card is correctly installed.
Check the connections to the vehicle.
Check the ignition switch position.
If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
Carry out the DATA LINK DIAGNOSTICS test. If the diagnostic tool responds with:
CKT914, CKT915 or CKT 70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418-00 .
NO RESPONSE/NOT EQUIPPED for DSM, go to Section 419-10 .
SYSTEM PASSED for the DSM, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self test diagnostics for the DSM.
If the DTCs retrieved are related to the concern, go to DSM Diagnostic Trouble Code (DTC) Index.
If DTCs are retrieved that are not found in the following DSM Diagnostic Trouble Code (DTC) Index, refer to the master DSM Diagnostic Trouble Code (DTC) Index in Section 419-10 .
If no DTCs related to the concern are retrieved, proceed to the Symptom Chart.

What did you find on the mirror? Do you have memory mirrors?

Change the switches, they are located on the door latch, this helps. i had the same problem and tried putting wd-40 and didnt work until i changed the switches. by changing the switches it stops saying on the computer that the doors are ajar.

You probably have a bad door switch that is located in the door latch.If the vehicle tells you which door is ajar I would try a good penetrating oil first and if not replace that door latch.It will take a bit of working the latch before it will start to work if thats all it is so have some patients with it.
