The bolts attaching the front door window glass to the window regulator may come loose. This can cause the window regulator to become damaged and possibly causing the window glass to break. Some 2003 & 2004 models have been recalled for the issue.

2006 Corolla has a rattle in the front passenger door. When I roll down the window the rattle stops. When I roll the window back up, it seems ok for a while until it starts rattling again at a later time.

Went to roll down my window and the glass fell all the way to the bottom. Took door panel off and the plastic clip that holds the glass was broken and the regulator bar was bent. Not sure how much this is going to cost to fix.
