Dodge Repair: 2002 durango front passenger window, power mirror, speaker harness

Question
One morning after a hard freeze I tried to roll down my passenger window but it was frozen shut. I obviously tried too long as something broke and now my window will not operate. The motor works but a square shaped piece of plastic that snapped to the door frame broke and the cables went slack. Cant figure out how the cables go now and was told that I can not purchase just the plastic piece that I have to purchase the entire assembly - is this true? If not do you know where I can get one??? and assistance on how to install and redo cables???

Answer
yes need a windows regulator assembly.
