Most likely the sliding blocks broke off and bent the window regulator arms? You will need to remove the door panel to access the power window motor. The motor comes together with the regulator. You should also order new sliding blocks as well. Once you replace the window motor you will need to have it initialized for the auto up and down function to work properly. Let me know if you need more info and good luck.
