If your door ajar light remains lit all the time, try spraying some wd-40 on the door latch. This really works! I just did it with my 98 Ranger and the Door Ajar light went off. Spray WD40 in the door latch for a couple seconds and it should fix it. I have a 96 Lincoln and the drivers door ajar warning light would do off and on and after a month or two, it would stay on all the time. I was outside the car looking in the car and noticed when I pushed against the upper right corner of the drivers door the light went out. Apparently the sensor for the light in located behind a small plastic cover in the body of the car. The inside of the door was quite dirty and I cleaned it and nows it works again. I just tried the WD40 on both door switches, IT WORKED. The door ajar light went out. Thank you!!!!!!!!!!!!!! i also tried wd40 on my latches. took care of the problem lickedy split. Genius!! 2nd Ford truck with the same problem (I sold the first one) and worked immediately. I had this issue on my 98 Windstar. It is with great joy that I can say HAD. The answer was going to a mechanic that had worked in a junk yard and had litterally dismantled them. They were fixing something else and I mentioned what a pain it was to have that bell dinging all the time. The manager said he had a guy that could fix it easily. The fix I have didn't involve touching the doors, latches, contacts, or anything like it. Not a door was opened except the one to gain access to the underside of the dash. In about 15 minutes from my presenting the keys to the problematic car, he went under the dash, found the relay that had the dinger attached to the end, and popped the dinger module off, leaving the relay to do its work, but silently. The relay is a cylinder about 1" in diameter, black, with a 1/8" hole in the center for that damn bell to ding from. It has a place to insert a standard screwdriver on the side along a joint (between dinger and relay). He apparently twisted the screwdriver which popped off the end which broke the two connections to the bell and then "SILENCE". He came into the waiting room, tossed the part on the desk and said the relay will never ever ding again. It didn't and hasn't even though the door is still "ajar". Relief. I can't speak for all the Ford dinging problems, but the Windstar of 98 has an easy fix if you can find someone that knows something. The best part is that with the dinger gone, I know it will never come back, kind of like cutting the vocal chords of a bad singer. Good luck to you out there, hope your fix can be this easy as well.
not to sure but on my vectra it normally controls the interior lights, but you have to pull the switch out to put the interior lights on
The interior lights are controlled by the headlight switch and are protected by a fuse.
you will find a switch on the panel to the right of the heating controls (near the hazard switch)
Beside your headlight switch in the dash is your gauge panel dimmer switch ( Rotate the switch all the way up to turn on the interior lights )
Most often this is due to an interior light being left on. Often it is the roller switch that controls the dashlight brightness and interior lighting being set to 'interior lights on'.
It has two. One behind the drivers side door panel and one behind the passengers side door panel. I just purchased one for my 2000 Ranger for $10 at my local parts store.
On a 1998 Ford Ranger : Try rotating the gauge panel dimmer switch all the way up , I BELIEVE that turns on the interior courtesy lights and the cargo light * in your dash , just to the right of the headlight switch *
Did you try turning the dimmer switch to a lower setting, sometimes the dome light will stay on even if the door is closed if the switch is set to high. But if the dimmer switch is set propertly, and the light remains on for a few minutes, the problem is most probably a defective relay. There are 3 relays on my 97 Ford Ranger, and I have not found out which controls the light. The relays cost too much just to buy 3 of them. If tou have tried dimmer switch and that did not work try using wd 40 on the the latches. The interior lights stay on until the switch in the door is cleaned and lubed. The switch is within door latches on for ranger. !
Possible headlight switch. Try wiggling the controls to see if it stop or gets worse.
There is a dashboard illumination switch that controls the brightness. If it is pushed up fully, the interior lights will stay on. Lower the switch slightly until the interior lights go off. When doors are closed, if the switch is lowered, the lights should go off after about 30 seconds max, maybe less. Hope this Helps, it did on mine.

On the interior lights for the back seats, there is a switch. When you turn the switch to "Door" mode it will make the lights turn on when the door is opened.
