So I was rolling up my rear drivers side window and all of a sudden the glass stops rolling up and its stuck at the bottom. I would crank it and it wouldn't go up. I pulled apart my door panel and this might be the problem...



I don't know what this piece is called but i'm guessing its this and if I find out what its called i'm going to replace it... thanks HT. Negative comments to yourself please

 

I think its called the window regulator.
