If it's the window crank assembly you are tlaking about, you need to pull the door panel off to get to it. You will need to have a special tool to remove the door handle as there is a spring clip that holds it on. The assembl will probably be rveted to the door panel. YOu can install small bolts when you put the new one in as the rivets are fairly large. You'll have to duck t tape the window in place and unbolt that, get the assemly out and put a new one in.
