Got a problem with my 76 Pinto's heater. This vehicle has stock AC. Heater hoses were disconnected by previous owner, I reconnected them, no leaking, but there is a vacuum valve in the hose, and I think it died. I'm not getting any heat, no matter what setting I put the valve, so I'm thinking that it may be the lever that adjusts from cold to hot. It is rusted up, and very stiff, and I do not believe it is moving whatever it is connected to.
Can someone provide me with a diagram or really GOOD instructions on how to manually open that door/gate/whatever that cable is connected to? Also, I also need to know what position the vacuum valve needs to be in to provide coolant to the heater core. It was in the down position when I looked at it.
Thanks, and a prompt reply would be helpful. IT IS COLD OUT HERE!
