99 Ranger, I could use some vacuum line help

Hey y'all, does anyone have a schematic of the vacuum lines for a 99 Ranger with the 2.5 motor? I don't mean the general overview decal under the hood, but rather one that specifically includes the HVAC lines. I have two problems... one being that I have no MAX A/C (recirc does not work) and the other being that the vac line is busted off the heater core isolation valve and I can't find the other end of it (the end that supplies vacuum to open the valve).

Thanks!

The HVAC has its own vacuum reservoir. It will be either a sausage like canister on top of the HVAC plastic plenum under the hood, or a round black ball about 5-6" in diameter. The location of the ball varies by year, engine and sometimes assembly plant. Look around for it the worst location used was between the passenger fender apron the the fender inner. In that case a small vacuum line protruded from it near the top of the wheel well into the engine compartment. As far as the vacuum line going into the passenger compartment, it is routed inside an electrical harness through the firewall. Try popping open the glove box and releasing the door stop to open it all the way. Look inside for a vacuum valve that controls the blend air doors.

If it only involves the recirc door then you'll want to focus on the white and gray vacuum hoses.
