Our drivers door on our 2007 Ford Focus broke and we were forced to open the vehicle from the trunk or use the key-less remote. After disassembling the door, this is the piece that I found was broken.
The bottom piece is the new part and you can see the little metal tab sticking out on the right that is not on the top part. It was quite the hassle to get the part into the door since there is limited room. Now the door works just as new and I am pleased with the part.
