I am fortunate enough to have the super high tech digital interior in my 1984 Buick Regal 
. I am a little stuck with the climate control system in the car and how it works. I believe it is vacuum operated using some of the lines in the photos below, but I can't be sure. Hard to remember or know what did what when the motor gets pulled and the engine bay was was basically obliterated...8 years ago! If anyone has any documentation or places to look on how to get that all working again it would be appreciated.
Thanks
