It is that simple, but the only hitch is getting to the center vent accuator. Its a really tight squeeze to get to it. I would suggest doing all of the pods. My center vent pod went bad a couple years ago. I pulled the dash and replaced the diaphragms all at once so I wouldn't have to do it again. The dash is pretty easy to get out. The service manual lays it out pretty well. And it makes the whole job a lot easier.
