Welcome to the boards, Vespira.

I've yet to have any trouble with my car's windows ( knock on wood ), but I've heard that the window regulator is most commonly the part that gets replaced when our windows start having issues. Well, more specifically, a small clip, but it's not usually available, so the whole assembly gets replaced.
Don't hesitate to use the search engine, and good luck with your Alero ! :thumbsup:
