Welcome to the forum

The switches are inside the doors, they are not the old plunger style used in the door jambs
The door switch Closes when door is open, and Opens when door is closed.
It is a Ground switch, so ground = door open, no ground door closed
So if you unplug a switch it would disable door ajar issue on that door


Try WD40 in the door latch, like this: https://www.f150online.com/galleries...633-119116.jpg

The front door switch is at the bottom of the latch so the WD40 runs down inside it and hopefully it will start working again

Rear doors are different, and if they are not closing tight then the door ajar light will be on and CORRECT, the rear door is ajar, lol.

You can take the rear door panel off, and reach down inside and unplug the door switch, its on the lower latch, so it can't Ground any longer and if that was the reason for the door ajar light it will be off now

On the front doors you have to remove door panel and then remove door latch to replace those switches, they twist lock into position so can be twisted with latch in place, but not as hard as it sounds

I know this is an old thread but hoping you can help. I have a 2003 ford ranger edge and the drivers side door does not trigger dome light or door ajar when open. I have removed the door panel and wiggled the cable and it works. I bought a new switch but for the life of me can not get the bolts loose for the door latch. Is it possible to replace the switch without taking all that apart?

No, door latch needs to be pulled back, the switch is removed/installed with a twist lock mechanism, so you have to be able to turn it to get it out and put new one in

Okay, thanks for the reply. I will look into tackling this but my door latch bolts are stripped so I may just have to deal with it. LOL
