I highly dought its the actuator itself... If you could give me a diagram it would be great... It sounds like either a lines not hooked up or possibly a dead solinoid...you should have either 2 or 4 solinoids on the passenger strut tower depending on the vacuum system, My money would be on theose befor the wastegate, and if it is, it's a cheap fix. To text them , just hook up power to them and listen for a click!
