Look for a switch on the a or b pillar where the door closes against it. It'll be like a small button with a rubber cover. If it's stuck, spray some wd40 on it and tap it until it starts working. You should be able to pop it out with a screwdriver. If you bridge the terminals on the plug with a paper clip or a bit of wire, the interior lights should come on. If the lights come on using this method but don't work via the switch, you know that the switch is faulty. If the lights don't come on it is a wiring issue.
