I have a 2001 EX. The door ajar light stays on and all the doors are shut. Even when you drive away the light still stays on for a few. This past weekend it started flickering, alarm would go off, and eventually killed the battery with the interior lights staying on. We just came home from Indiana and while driving the door ajar light would come on and off, luckily the interior lights wouldn't. Any idea what may cause this?
