    Have a 2003 navigator, the driver power running board will only drop down when rear door is open, the mirrors are also wanting to fold in on their own, can these issues be related?

    2004 ultimate. driver side - only - would sometimes come out, sometimes not. i tried opening just the back door & it would come out - sometimes. passenger side worked find. the problem was the control module, replaced under the extended warranty. to date, owned truck 4 months, 15 days in dealership, :sick: estimated $7-8k repairs under extended lincoln warranty, :mad: $200 out of pocket.

    The mirrors wanting to fold on their own:
    An issue in the control module for the power fold option.
    Something is causing the signal to be sent to it to tell them to fold.
    Maybe contact spray like CRC electrical contact cleaner sold @
    Walmart spayed into the backside of the master window switch
    power mirror fold button could solve this problem.

    I’m thinking the running board may be the door latch because it also won’t turn off the stereo or turn on interior lights when I open the door, I’ll go to a junk yard and look for that control box though

    BCM
    Body Control Module

    I have an issue with mine in the F250.
    Constant power drain, it's in most of them 1999-03.
    No more available thru Ford and any pick-a-part
    are a roll of the dice to get maybe a good one.

    Wife told me on an out of town work trip the power
    locks just kept cycling up-down up-down till the battery
    died. Killed the actuators on all 4 doors.

    Thanks for the info, there is a slight draw if I don’t start the car every couple days the battery does die , if I get a new BCM will I need to have my keys reprogrammed?

    No, BCM only controls the peripherals connected to it, ie
    lock actuators, lighting controls, the running board board.

    DDM, Drivers Door Module, located above and left of the fuse panel.
    It has the code on it for the keyless entry.

    Good luck, they built over a million F250 at the Kentucky truck plant.

    I see repair services for the bcm/fuseboxes as it looks to be an integrated unit.
    For the info I see some are in the passenger kick panel, same as the F150s in those years of production.
    Some early models had fuse panel driver's side left dash.

    Fuse box is on passenger side, so that whole piece needs to come out? Sounds like a lot of work lol

    Replace driver's door latch and see what happens.
    I sAy it has the most open close cycles wear factor.
    Maybe you get one with better contacts or try to
    CRC contact spray clean the one in it now.
