2002 Ford F350, Door Ajar Light on constantly, Auto Locks don't operate, Auto Headlights don't operate(only manually), Dome Light does not operate when opening doors, Remote does not work. All

I know the problem. Mine does it too. The fix is easy. Open & close doors to find which one is causing the problem. Open that door panel and find the release latch at back of door. There are 2 wire harnesses attached to the latch. Unhook the wires and spray sockets of latch. There is a ballbearing that gets stuck in switch. Lubricate that ballbearing and work latch manually several times. This problem will reoccur occasionally especially when there has been a lot of rain. Good Luck

I'm pretty sure that they are integral to the door lock assembly on that model, would need to replace the whole door lock if that is the case. Best to get the Ford dealer to plug in their computer and check the signals from the door locks to see which one is at fault. Check central locking and power mirror fuses first, if no power to door locks then the door ajar sensors will have no power as well.

SOURCE: my passenger door has no power,my security light is on constantly

Have lost power to the passenger side door. Without power system doesnt recognize door closed because of no power to door ajar switch which keeps dome light on. Security light stays on because without power to rest of systems supplied by fuse it cannot tell if doors and windows closed to engage security features. Most common is for power wire to break somewhere near where it leaves to main body and enters the door.
