My 2000 Ford Excursion XLT 6.8 V10 Auto Trans. keeps the interior
lights on for about 40 minutes after I park & close door. Also the lights
stay on while driving, which annoys me when I drive at night.
Any simple solution without taking it to a Ford dealer? Any suggestion
would be appreciated.
You have a door adjar light sticking in one of the doors or deck lid.
Take you a can of WD40 open each door and spray it into the latch on the on the side of the doors then open and close it a few times,this will take car of the problem most of the time. Start with the driver door first it is usually the one.
Well so much for the easy stuff.
Now its down to the GEM module,interior lamp relay,battery saver relay, or the interior lamp switch(on the headlamp switch).
Here is how the system works.
Illuminated Entry
Illuminated entry is activated when a keyless entry keypad switch provides an input to the GEM or when the GEM receives an unlock signal from the remote keyless entry transmitter. The GEM then activates the battery saver and interior lamp relays by providing ground to the relay coils. Illuminated entry is deactivated when the GEM receives a lock signal from the remote keyless entry transmitter or if the GEM receives an input from the keyless entry keypad. Illuminated entry will also be deactivated when the GEM receives input voltage from the ignition switch.
Battery Saver
The battery saver is activated when the GEM is not receiving voltage input from the ignition switch (off position). The GEM will then provide ground to the battery saver relay coil, activating the relay, for a period of 10 minutes with the interior lamp (headlamp) switch in the off position, or a maximum period of 45 minutes with the interior lamp (headlamp) switch in the on position, provided that the GEM does not receive any other input signals within the time-out period. The activated battery saver relay switches voltage to the demand lamp circuit and the interior lamp relay coil. After time-out, the GEM disconnects ground from the battery saver relay coil disabling the demand lamp circuit.
Are you sure that the interior lamp switch on the headlamp switch is not turned on? That would would explain why it is taking 40 minutes to cut off. Usually the battery saver relay will turn it off in 10 minutes otherwise.
You can try swapping the interior lamp relay and battery saver relay and see if that makes any difference. They will be the 2 top smaller relays in the interior fuse panel. The top one is the interior lamp relay and the 2nd one is the battery saver.
If you don't find anything there I would suggest its time to let the dealer look at it.
Oh almost forgot the easiest thing of all!
Check fuse 14 in the interior fuse panel (15amp)

Thanks, Chuck.
The solution did not work.
By the way, the lights on the running boards also stay on after the engine is shut off. But the 'door adjar' indicator lights do not come on, unless a door is actually not fully closed, whis is not the case it seems.
same thing happen to me but the dash said door open or something like that but i just take the fuse out
My interior lights on my 1999 ford f150 stay on after all doors are shut. They do eventually shut off after 5 minutes or so. Very annoying
I have the same problem with my 01 Expedition. Interior lights would stay on even no the ajar door light is off on the dash. I pulled the #14 just so its off. Could it be a relay problem? I looked at mine and relay one is white and relay two is black. Not sure why.
This problem seems to be the same as mine. I have a 2001 Excursion. The interior lights (and running board lights) stay on. There is no apparent door ajar issue. The lights are on but in a "dimmed" state. One can clearly see the difference between this "dimmed on" state and the "fully on" state that occurs when the remote or door keypad switch is activated. Locking the doors with the remote or keypad (when the lights are supposed to turn off) return them to the "dimmed but on" state. The issue occured when I was traveling down the road at night with no one touching any switches. The only way I have found to bypass the issue is to remove the #14 fuse. I have not tried to wait the 45 minutes to see if the battery saver feature turns the lights off.
