How do I fix a Loud bang and then my power window quit working on my 2010 ford f150 pickup drivers door?

The loud bang could indicate a broken window regulator or a snapped window cable. First, check the fuse for the power window to ensure it hasn’t blown. If the fuse is intact, remove the door panel to inspect the window motor and regulator for damage. You may need to replace the faulty components to restore functionality.
