i just bought a 2005 titan. i have only had it home for a day but I sure like it. i have a question for everyone. this might sound dumb but .... are the front windows supposed to go all the way down? they don't. i push the button and they go most of the way down, but stop at the 3/4 mark. both side. what the heck. i want to hang my arm outside the truck, and i cant! any one know if this is normal, or is something wrong. if something is wrong, what would that be?:huh:
