dont waste you time and money, how many bad ones do you want to repace?its not that high priced. you should be able to buy that from any AC DELCO distributor. log onto the web and search AC DELCO and find the nearest one. the desler can tell you what other car lines use that part.
SOURCE: Drivers side blend door actuator not working
Hello: I have bad news for you, if you run the actuator without it connected to the door the actuator is ruined, it will have to be replaced. After replacement the system has to have the doors (actuators re-calibrated.) re-calibrated. This is done with a Tech 2, A GM special tool.

Yes it is most likely a vacuum actuator there are more then one . They open and close little doors in the ducts to deriect air flow inside the ducts . They are not easy to get at in most cases however you should look at all vacuum lines going to and near the unit its controlled by engine vacuum . exhust all other opptions first before takeing the dash out . The problem could also be electrical check the control switches make sure the switch is not bad on one side . Spend some time looking and thinking before you start riping things apart. Good luck with it

This job requires the complete removal of the dash from the car and dis-assembly of the duct work to replace the blend door. You must have a factory manual to have any chance of not messing this up completely.
