Re: AC Pneumatic Lines Routing
Thank you all for your help. For the benefit of someone else with the same question:
Using my Mityvac to pull a vacuum I tested all options of vacuum draw and which ports are open when the climate selectors are made. It seems the drawing posted above is correct when you follow the numbering on the manifold, which is numbered clockwise. You cannot see it unless you remove it from the dash.
1 Actuator on firewall primary line
2 Actuator on firewall secondary line
3 Manifold vacuum
4 Actuator to direct air to defrost
5 Actuator to direct air through AC ducts
The only thing is I don't understand two lines routing to the engine bay dual line actuator. As in, why are two lines needed? Ports 1 & 2 route to it and either 1 or 2 or both will draw the actuator to swing the door. I believe I am going to assemble this "correctly" but put a plug in port 2 line so fresh air and recirculated air will work correctly.
