i have a 2000 convertable and i just had to replace the window in it. it was working good for a while but now it keeps going crooked when lowered. it also pops. i think the rollers came out of the rails. i am going to lube the rail up good and try it but if it doesn't fix the problem will this be covered under my extended warranty. is everything in the door covered. i did try to adjust the rails using the torx studs and set nuts on the rail.
