I have the car listed above, I could really use a climate control cabin vacuum diagram with replacement part number for upper and lower actuator motors. The dealer and Alldata do not have the correct information.

Single zone or dual zone system? There are about twelve diagrams for the various systems so narrowing it down might help get the correct one.

Dual zone, I have found AcDelco 1573289 as the "lower actuator" at Rock Auto so I assume there is an "upper actuator" as well. Thanks for your immediate assistance, you have no idea how appreciative I am. I have been trying to find out this information from the dealer I bought the car from, but they have little interest or no information. I cannot tell which.

Steve, I can't tell you how many hours I spent trying to find exactly these diagrams. You are spot on. Pushing my luck a bit, are you able to source the part numbers for any of these items, especially the actuators. You have my deepest of thanks at this moment

This should show you all the various pieces and part numbers for the HVAC system. Being a 1997 some parts are likely used/Ebay only.
