I have a ford ranger that has a broken vent, it's the tiny one to the right of the stereo is usually where it is .what is the name of it so I can order a new one?
You need to at least specify the year and model of your Ranger. Assuming you mean an old Ranger, there are three generations, each of which has a different dashboard. Engine and transmission doesn't really affect this within generations to my knowledge- unless what you broke is part of the center bezel and you have a 4×4, not a 2x4. It also covers all bases, and is a requirement when you ask questions- it's stated at the top of the page.
Pull it out and there ought to be a part number on it somewhere and go from there. Or just go to a junkyard that has a Ranger and pick it up there. easy peasy.
