Door adjar warning light stays on. Dome and cargo light stays on.

your doomed

One of the switches that gets pressed in by the closed door is bad.

Remove or replace the relay for the interior lamps. Ford is notorius for having this problem

the door adjar switch is the problem. the cargo light stays on until 35mph, as well as the overhead dome light. i just took the bulb out of the dome light and dont worry about the cargo light. it stays on for 30 min after the truck is turned off if the switch didnt trip properly. it shouldnt cause any problems as long as your batteries are good. i havent replaced the switch yet but it should be on the part of the door by the latch. get the replacement part and do a visual I.D. when you get the panel off. then replace it. the sensor is only 14$

At least one of your door ajar switches are sticking. Try spraying rust penetrant into the latches and open and close the doors several times. If they still stay on you will have to locate which latch it is by removing the door panels and disconnecting the switches.

Hello! The instigator of this problem appears to be the the rear cargo lamp; Official name is rear dome light. You'll need a multimeter set on the X10 ohm scale to shoot this trouble. Leave the rear dome light bulb out. There are two switches involved; #1 the rear dome light on/off. #2 the right hand front door switch.

Pull the horn fuse out, remove the rear dome light cover, drop the rear dome light down to access the wiring and close all doors on the vehicle. Connect one lead of the ohm meter to the white wire and the other to body ground. If you read any resistance one or both of the two switches (dome light switch or right hand front door switch) is remaining closed when all doors are closed. Next disconnect the black lead from the dome light switch and see if reading changes to zero. If it does this is indicating that the dome light switch is defective. If it does not, disconnect the right hand door switch and take another reading at the same location. If you still measure any resistance, the black wire of the rear dome light is shorted to ground, if not then the right hand door switch is the culprit.

The reason the right hand door switch and not the left hand door switch is involved is the fact that opening the left front door would turn on the front dome light as well as the rear light. If both dome lights are staying on with all doors closed I would then involve both door switches in this test procedure. If your vehicle is a four door model then disconnect one door switch at a time while performing this test procedure.

The horn fuse also supplies power to the rear dome light, and I suspect the two events are related.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

Your courtesy fuse is blown. Look under the hood fusebox. There should be a fuse labeled CTSY (10amp). If blown, you have a hot wire touching bare metal.

Check under the hood, in the fusebox, for a fuse label ctsy (courtesy). It'll be over the driver side wheel. Replace it, if blows and, you have a wire touching bear metal somewhere. Good luck!

the latch may need to be cleaned from dirt and dust then sprayed with penetrating lube. It does require removing the latch from the door.

You may have a bad door switch. The alarm is usually wired into the door adjar switch amongst other things. If the alarm system is being told that your door is still adjar due to a bad switch in the door jam then it's quite possible that the alarm system will not operate the locks if it thinks the door is adjar in which is also evident by the dome light staying on. Sounds like a switch. If not the switch then I would lean more towards the alarm system being responsible.


Good Luck. I hope this has at least narrowed down your search if not pinpointed it.
