http://www.grandprixforums.net/showt...door+actuators follow this how to open up your car so you can see the 2 round vac pumps. car running work the controls watch the arm off the vac pump for it to move. you should be able to move it by hand if its not moving. MOVE IT CAREFULLY or it can break the plastic parts. id turn the car off if you try to move them by havd so theres no vacuum pulling on it.
the vac pump is shown in the first pic there, its the round part in the lower right. theres on one the pass side too, its in the same place. mirrored. they both need to be checked.
