You could also have a parasitic drain on the battery like I did. The 'Door Ajar' switch would cause interior lights to stay on or even go on later when no one was around. The answer I found was to stick the straw on a can of WD-40 into the door lock mechanism and give it a couple shots. Problem solved, and it was very easy.
