Hi,

I do have a vacuum schematic for the emissions control systems. Also, the HVAC actuators are controlled by an engine vacuum.

Pic 1 below is the emissions system schematic and pic 2 is related to the HVAC circuit.

If you are looking for a leak, here is a link you may find helpful:

Let me know if this helps or if you have other questions.

Take care,

Joe
