reading that makes me think it is something with the track or motor...i have in channel vents on mine, and the first couple of weeks the motor sounded stressed as it closed and had a creaking sound, but that went away...bwarren228 said:I wish my problem was just window vents. I have no vent visors though and it still makes a bad creaking noise when it goes all the way up. Going down, sometimes it seems to jump or skip a little part of the way down. I'm wondering if its slightly off track or something. I'll probably have 2 take it to the dealer and see what they can do for me.
