Inside lights will not turn off. Bypass?

Possible defective door ajar switch. Usually located internal to the door lock mechanism inside the door. I have had some success spraying WD40 inside the lock assembly with the door open and then opening and closing the door several times.

Can you swap door switches from left side to right side to possibly eliminate one side?

the problem is door ajar switch located on one of the door latches just inside the door. what usually works is spraying wd40 or an electronic lubricant prayed liberally into the door latch and then opening and closing the door several times. the stuck switch is usually on the door that is the least used door like the passenger side rear. let us know how you make out.

The door switch is stuck on or the wire is shorted to ground.

What happens when you remove both switches, and wires? What happens when you use a jumper wire acros both wires, on both doors?

there should be a switch mounted( or more than one) in the door jamb that tells the car when the car door is open...i will probably look like a little plastic plunger...might be broken off or bad internally

Check the DOOR BUTTONS in the Jams One is giving the signal for Dome Light and usualy you can Just Roghly Push and reliece them and they get the right connection

inside the doors is a Small twist in button switch on the door latch assembly that turns on the doom and key buzzer, they stick and make a poor connection, this causes your problem, i have replaced 100's of them, u will have to detrim the door to get at it. The switch is about $10 and u can get it from most parts stores, here is a picture. remember there is one on each door latch.

I had this problem on my 2003 explorer and took WD40 and gave the lock mechanism a good dose where it meets the clasp on the door jam. Then open and close the doors a couple of times to get them working. They get gummed up and sometimes have a tendency to stick.

These switches are inside the doors attached to the door latch assembles.If you know some one with a scan tool you can go into the body computer and see which one is showing open when all the doors are closed. The most likly one is the drivers side door or the two in the rear gate. I've replaced those the most.If you don't want to replace them you can unplug them and the lights will go off. Hope this helps. If you need more info let me know> Thanks Dan
