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.
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'.
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. !
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 *
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.
Possible headlight switch. Try wiggling the controls to see if it stop or gets worse.
On a 2001 Ford Ranger : Rotate your gauge panel dimmer control all the way UP ( that turns on the interior courtesy lights and the cargo lights ) * located in your dash next to the headlight switch

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.
