Vacuum hose diagram for heating/AC

[Cristóbal]

I have a 2005 Ford Ranger 2.4 l engine, manual transmission, AC Does anyone have a diagrams showing the vacuum hoses to/from the switch for various vent/air conditioning? I have removed part of the dash, that is to say, the center panel where the ventilation/heating/air conditioning switches are located. When the system is set to AC, the cool air comes out around the base of the windshield instead of through the vents. Tinkering around a bit I found that there does not seem to be any vacuum available at the switch. A connector goes through the firewall but I do not see where it comes out in the engine compartment. I suspect that a hose is loose or leaking somewhere. I do not hear any "door" sounds either. This condition has worsened recently. For a considerable period of time there has been no heat but the air conditioning worked fine until recently. If I could get a diagram of this system I think that I could trace the problem(s) down. Anybody got any information on this?

^^Should find it there.

FYI, your accumulator is under the airbox, bolted to the fender liner.
A black plastic sphere with two vacuum hoses.
Inspect them.
The rubber fittings on the sphere are checkvalves.
