Every 2-3 months I would spray it and the problem would go away but about a month ago the wd-40 would no longer do the trick. If the splice is made in the door jamb it will break again very quickly. You can spray all you want into the latch area but you will probably not hit what you need to. In order to remove the latch assembly and or the door ajar switch the lower window track will have to be removed. This problem is intermittent, but seems to be reoccurring more often now than before. This keeps just the lights and chimes off. Everything was back to normal.
These faults could be related to the door ajar switch sticking. To install the new switch push the switch into position and rotate until click is felt. After removing the switch, I found I was sent the wrong part. I had the same problem with the door ajar light. I have seen this before on the explorer and what I have found is the door ajar switch located inside the door panel, mounted on the door latch gets stuck and what I have found to fix it is spraying wd40 onto latch and opening and closing the door several times usually will work the wd40 into it freeing it up. So I suggest replacing the switch.
But it was too late by that point to be able to buy one since all the parts stores were closed. If it is not that switch, work your way through other doors. I would love to trade it in, but no one will give you anything for them. You can spray all you want into the latch area but you will probably not hit what you need to. I also had sticking door switches that made things cmplicated. Is there a trick to this. Quick tip read the stickies at the top of the forum which specifies the year of your vehicle.
Doors will lock and unlock by themselves, and alarm will go off for no reason. If it works, the light should go off in about 30 seconds, and the door ajar light will go out. The 2 map lights did work. It is mounted in a fairly large rubber insert. There are two screws at the rear of the door. Try adjusting the striker closer to the pilar. A sensor appears on each of the four doors, as well as the tailgate.
One charges Ford more for their parts and one charges less. The door ajar light remained on after the other lights went off. It is fairly easy to fix. If this doesn't work, you could remove the door panel and do the spray treatment from the inside also. That's why the radio does not turn off on exit.
Until I figure this out I have removed the relay located over the driver side rear wheel well. Just move the switch down slightly and your dome lights will turn off if all your doors etc. I have replaced mine on both front doors and there is a new revision of the part from the original, never had a problem since replacing. With all the windows in the down position, activated the alarm and waited about 30 seconds. I also gave you the fuse panel, if you pull fuse 27 that should turn your dome light off. If you don't have a wire repair kit pick one up at your car pa store or harbor freight there less than 20 bucks. Don't bring it to a dealer you can do it.
I am also having a problem where my interior lights don't go out after the car is off and the doors are all shut. I had the same problem on my '03. Give it a few sprays, then open and close the door several times. I just want the problem fixed, it's quite annoying when you doors start locking and beeping out of control for long periods of time. I also had problems with the door ajar light on, no windows would work, the running lights quit and had to turn them on manually, the radio would not shut off. The dashlight then grounds itself through the interior lights.
Could also be related to the door ajar switch. I have a 2002 Ford Explorer, the Eddie Bauer edition, and for about the last year or so I've been having issues with the door ajar light and alarm. If I open and reclose my tailgate door it will stop beeping. Be precise on which side you need it because each side has a different part and they will not fit right on opposite ends. If the warning lamp is intermittent, the spray repair may just be coincidental and actually have no affect. .
This will disable the interior lights as well as the running board lights good , but it also disables the power windows bad. It's wonderful slamming the brakes on going down the road thinking one of your children is trying to jump out of the car and it is just the sensor!!!!! This will, however, solve the problem of the lights remaining on after the doors are shut and running down your battery. I found 2 broken wires and repaired them. When this happens my puddle lights and interior lights stay on after I leave the truck for about 20 minutes. Any input is greatly appreciated. That should tighten it up enough to make the door ajar switch function. Most recently all 4 windows stopped working.
