2003 Ford F250 V8 Four Wheel Drive Automatic 85000 miles
Crew Cab Lariat V10 Super Duty. The door ajar light and dome lights stay on all the time. A dealer had a computer hooked up to it and the computer says all 4 doors are shut while the door ajar light stays on. I have had the instrument panel, GEM, junction box and the driver door switch replaced with no result. Can you suggest where to look for the cause.
I usually find the problem to be the door ajar switch in the latch of the door that is least used. To repair it all I do is spray brake cleaner inside the latches to remove the dirt and oil then I spray the hell out of it with wd40 then open and close the door a million times. Its either that or a wire rubbed through somewhere.

Spray the latches with a light lubricant such as wd-40. That usually takes care of the dome light issue.
