2004 Ford courtesy light in cab stays on all night, need a boost every morning.
It is supposed to go out if the light switch is turned to half way but this one never goes out unless I disconnect the battery.
Common problem, often caused by the door switch which is located inside the door latch that starts to stick on.
Sometimes freed by squirting some WD-40 into the latch on the door. Sometimes the entire latch must be replaced.
Ironically however the vehicles body control module should be timing out the light after 15 minutes.. May have issue with the body control module, on some Fords this module is integrated into the top of the fuse box located underside of the drivers side dash..
The problem of the Body control is often traced back to your windshield leaking on the driverside, the windshield just happens to be directly over top of the body control module!
If body control malfunctions, don't be surprised to have other things like radio, windshield wipers and fan motor to act up..
