I have been doing quite a bit of browsing and have made good headway in preparing to tackle HVAC under dash vacuum lines. I have a chart for the automatic system but I am having trouble finding a chart for the manual system. (Non RPO C68) Can anyone post one here? The image is for the auto system and looking for something similar to that so I know what is supposed to happen on each setting. My problem right now is heat/defrost is fussy and the slave unit and fresh air door are fussy. Just not sure what is supposed to open when. Thanks.
