86 heater valve

The heater coolant valve under the hood on my 86, which is vaccum operated, does not move, whether I am in auto a/c mode with max cooling (60deg) or with the heater on full (85deg). There is no vaccum going to it. Before I trace the vaccum line, I just want to know which way the valve handle should be pointing to cut off coolant flow to heater core? The valve handle normaly points forward, and when vacuum is applied, it pulls back and points straight up. I would assume straight up shuts off flow. I have a 50/50 chance of being correct!
