My 4wd severice light comes on and will not go in 4wd at all. I have replaced the buttons on the dash. Still did not work. Where is the vacuum actuator?

The first thing to do is scan the transfer case control module for trouble codes, there will be a code stored. Transfer case position sensors and encoders have had some issues on many others just like yours. Let me know the codes and I can give you a starting point for diagnosis.
