Usually, this is what we in the trade call "smoke in the cockpit". In other words, either someone has fiddled with your dash light switch and left it in the courtesy light "on" position, or someone has turned on the map light switch. Check both, and if you don't find the trouble, disconnect your battery when you park until you track it down. Start with the door jamb switches(take them out of the panel and pull the wires off to see if the lights go out.) All the wiring date is in your service manual. If you don't have one, watch eBay or contact one of the IML literature vendors, you need one!
