Can someone show me where the vacuum lines from the AC/Heat control goes. Do not have a clue where it gets plugged in at.

I am not a mechanic but played around with one vacuum line that does give you vacuum to the system. From a driving position, one vacuum line runs from the left rear top of engine (reachable with removed inside cowl) to behind the right headlamp. This line runs across the engine (why GM did this??). It dries out cracks and poof goes your vacuum. I found using a standard vacuum line (over each end seemed to work fairly well if you don't want to fight with the newer thin lines. There are others lines but you might check this often faulty one first.
