Why would the Door Ajar light stay on and the interior and running board lights come on each time you come to a stop in a 2000 Ford Expedition?

Hope your well... I had the same problem with the door ajar light. After taking everything apart and no luck. An Old Timer Mechanic told me to spray WD-40 on the door jams and locking device guess what it works. Almost a month know and it still works. ... Al52269

that is the trick had the exact same thing happen and it will start to happen about every 6 months used a teflon spray lub from walmart and now its been over a year with out issue.

Could also have a bad realay in your fuse box.

I am not a mechanic, however as an electrician it sounds like the running board lights are wired to the same relay as the interior lights. To check this, simply crank the truck, leave all the exterior lights off, turn on the interior light, then walk around the truck and look at the running board lights. If they are on then turn the interior light off and the parking lights on, check to see if the running board lights come back on. Depending on the make and model of the truck, I could be way off in left field and this info may not apply. uuummmm.....programing?

the fuse that controls the interior lights, running board,an rear wiper is blown. it is a 15amp fuse in the panel. Also,try the cluster dimmer position since it controls the running board lights and exterior mirror lights as well.This dimmer is located next to the headlight switch.Good luck!

I had the same problem. On my 1998 Ford Expedition XLT. Spray WD-40 on all the door jams. This should take care of problem.

Probably one of your door switches. These are the little nipple looking buttons that tell the truck when to turn on the lights (when you open the doors). You should be able to push it shut with your finger and see if there is still voltage going through the switch to tell which one is bad. There is no real short cut for this.
