[W126 Coupe] who has the HVAC diagnosis scans handy?

[Richard Shayegan]

I don't have my service manuals handy. Anyone have the scans of the HVAC 
diagnosis handy? Or, if anybody is a real wiz with this, which vacuum is 
bad when the open triangle A/C doesn't put air out the center vents and 
does put a lot of air out the defroster vents (same goes for the EC 
button) and the filled-in triangle A/C makes air come out the center 
vents and a very slight amount of air come out of the defroster vents?
