99 Alero Heater Blend Door Actuator

[gundam94]

My 99 Alero has a bad blend door. I get cold air when I have the heat turned on and being in WI this is a problem. I need to get at it so I can open the door the actuator is supposed to myself. I think it's in the dash and I am thinking it's behind the radio or at least in the center of the dash. Beyond that I have no idea what to look for or even how to get at it. So basicaly I need directions on how to get at the blend door actuator, wear the actuator is at, and anything else you guys think I need to know.

Pull the glove box. The actuator is on the left, it'll have a plug that runs to it a two screws that hold it on. Hopefully its just the actuator and not a broken door. If you leave it plugged in when it's out and change the temps you can watch the actuator move(or not).
