My open door light is on my dashboard, but all doors are closed. How do I fix

THE DOOR IS POSS NOT ALIGNED PROPERLY

The car only senses that the door is closed if the door is pushing the "door closed" switch. This plunger switch is located inside a rubber boot (it looks like a bumper stop) near the door catch post in the door pillar. The switch is either damaged, or the door is not pushing the switch. To test the switch push in on it manually (you should be able to feel a spring-loaded plunger inside the rubber boot) and (with all other doors and hatches closed) check to see that the dome light goes off. If it doesn't, replace the switch. If the switch is working, then the door probably needs to be re-alligned so that it pushes the switch in farther when it's closed.
