Dash A/C blows out top like defroster. Exploration shows broken vacuum line at fire wall going off to left. Where to find a manual with pictures &/or a 82 Honey owner's manual or both. Thanks
Is this coach a Class A or Class C (Econoline van nose)? I can go look at my '84 Ford 460/Class C tomorrow in the daylight if you like. But first, Is this Factory Air? Mine looks like factory air but it isn't. Giveway in engine compartment is clamped hoses, not crimped. Inside, it turns out the cooling coil is inside the dash duct, there's an extra blower inside, and control head is modified with a little switch to engage the compressor. I don't think mine has much of anything in vacuum control, but as I say, I'm willing to look. Unless somebody helps you first and I don't have to crawl! God Bless, jd

That broken vacuum line has another end, coming from the vacuum reservoir, a round object, about the size of a large grapefruit, and usually black. Find it and trace the hose connected to it. Following this hose, you should come to a "tee", from this "tee" will come a hose leading to either the intake manifold or to a vacuum manifold that will have a hose connected to the intake manifold and several other vacuum hoses also connected to it. From the "tee" a hose leads to a vacuum "gang" connecter, that is, a group of vacuum hoses connected to a plug-together connecter. There is a check valve in the "tee", between the vacuum source and the reservoir. This check valve prevents the vacuum in the reservoir from venting back into the intake manifold when the engine experiences low manifold vacuum, such as occurs under a hard pull or sudden acceleration. If it were not for this check valve, the vacuum motors controlling the different air flow doors would cease to function, causing airflow different than that selected via the control panel.
