Over the past month I've noticed a rattling noise when going over slight vibrations or accelerating for about the first 2 miles and then it goes away. Seems to be in the area behind the driver side vent (closest to the door) or in the door itself where it meets the dash when closed. Any experienced this? I've tried putting pressure in areas all around this and it doesn't go away until the truck runs for a few minutes. Only really notable in mornings or after resting cold for a while.
