Sorry for the late reply.
Yes, I believe your headed in the right direction. Have to check actuator and vacuum. In the diagram, should be number 5 actuator.
I realize this is an old post. In the future, hope you have any vehicle issues, but, if you do, keep the site in mind. They are always trying to improve the site and it's free.
Have a good day.
