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.Google+

Front drivers side window gets stuck and won't open.
Need to again repair passenger window as plastic connector between regulator bolt and glass fractured in half. Can't just buy replacement plastic saddles for glass but rather GM will only sell me a $400.00+ window!
I brought it to dealer after getting a notice and it was taken care of
