Since people are always asking how to fix their dome light or door ajar light from staying on. I thought i would make a post showing how to fix it.
If the light is on and the doors are shut then spray some WD40 in to the latch. The door switch is probably stuck.
Spray in both doors then open and close them a few times. sometimes you will need to spray a lot of WD40 and it will run out the bottom of the doors. Just leave them open until it drains out.
