I previously owned a 99 GT for 3 years and had seldom issues. It was totaled in an accident and I bought a 2002 GT with all the options. I've had crazy issues with the windows since I got it. The drivers window used to not roll up unless I coaxed it while pushing the button. Now it just falls down on its own. Like it's loose in there and off track. What do I need to fix it? Regulator and ???? If anyone knows of a tutorial or info on repairing it that would be great.
