I have been searching for a diagram that shows what cables connect where and what setting on the control panle moves them and what they should really do. Does anyone know where I can get such a diagram???

FSM (Factory Service Manual) is about as good as it gets... You DO have the FSM on hand as a reference or no? Will be listed under the Air Conditioning/Heater section...

If you don't have the FSM on hand you can get it from the following url:

OR you can do a SEARCH on this site and see just how much information IS out there.

I did the same search and found several references that would allow you to deduce what to do. No diagrams, but several point by point descriptions.

Use the terms: "Heater and Control and Cable" in the Search window (including the word AND) and you'll get a couple of pages worth of posts. Some of the information will be for the Early and some will be for the Later Z. Not sure if yours is strictly cable controlled or if it also uses the Vacuum system of the later cars.

I'm suggesting you do it this way rather than just posting the results of the same search so that you can find out just how MUCH information is in the archives.

FWIW
