have 2001 chevy impala and my front windows keep poping out of track and window will not roll up?

Usually the window regulator is broken. Look at the way the regulator is, sometimes those clips break. Cant remember if Impalas used the plastic retainers on the windows. I think those were the older days

Sounds to me like the window jumped the song. The humming you heard became the skill window motor attempting to close the window. it certainly relies upon on why the window jumped the song as to how costly the restore would be. each so often you get fortunate and all you could desire to do is take the door aside and placed the window back on the song. it somewhat is definitely much less stressful reported than finished on maximum autos. although if the window jumped the song because of the fact of an element failure this could cost you greater funds.
