My passenger door light flickers when I am driving and also when the car is off. I've noticed in the mornings before I go to work that it is on and may be on all night. The door is always closed, and there are no warnings on my dash about an open door or anything like that. The main problem is it is draining my battery. I just had to put a new one and am afraid it will just drain this new one too. Any easy way to make it stop or do I need to take it in? (2006 model btw)
