I just bought this car used a couple of days ago, so I'm trying to figure out something that I missed before I bought it. Sorry if this question has already been asked. Whenever I open and close one of the doors on my car, the headlights flash. It's a consistent 1 second interval and it does it for somewhere around two minutes each time before it stops. There's no security light lighting up on the dash, nor are the hazards lighting up. When I turn the headlights to the ON setting, they remain on and do not flash. How do I stop the headlights from flashing?
