My passenger window is messed up. dad rolled it down today. then put it up. something clinged around and fell in the door. itll still push the window up and down but not straight or fully.

I'm not sure if the Aleros use clips or a track, but either way it has or something has fallen off to hold it in place... Pull the panel and you should be able to figure it out pretty quick.

A clip broke.....use the search there is a pretty extensive write up on it w/pics, and part numbers.
