Okay, this is the first cold season I've had with my 05 Titan and I am experiencing some issues with opening doors in the am after a night in the teens. They aren't frozen due to moisture but it seems that something in the door isn't working properly due to the cold weather causing my doors not to open or once they open they wont close. Anyone else experiencing this? Is there a way to fix this without taking it down to the dealer? Any help would be great!
