Actually with a little further looking the FSM is good and there are several good threads here already regarding. Thanks

Those 71 valves are famous for leaking. Had friends buy NOS ones and they started leaking. If you don't care about being correct you might consider using a 70 and up A body valve. Easier and cheaper to fine. Last a long time. StratOvent cars use a different expensive valve so use the A body valve.

Sounds like the control switch is bad. I think someone makes new reeds for it or find a new switch. Sound like the temp door actuator is not working along with the heat/defroster door actuator also. Default mode meaning if the system loose vacuum is hot defrost. You can check everything with a vacuum pump.

Changing the heater control valve, or even having the wrong one, won't affect the switching of airflow in the dash. Sounds like either the vacuum switch at the heater controls isn't working or has one or more broken off nipples, or there's a vacuum hose popped off one or more of the actuators on the heater box. Those are a PITA to try and check with the dash/heater box in the car. Hopefully, the photos I posted of my extra heater box will show you which hose goes to which valve. Thanks for the insight. I'll check the hoses again, more closely as well as all the nips This is my.first time working on a vacuum system. Hoping the vacuum regulator IS bad, unless of course it's non available and I hope to score a new one.? Thanks again. Tommy

Default mode meaning if the system loose vacuum is hot defrost. You can check everything with a vacuum pump. Mark, yes this is my scenario other than that the air only flows through the A/C vents, not hot defrost. I can add that after I installed the new vacuum water valve, now the system is blowing only COLD air, even after normal operating driving distance & conditions. Is it OK to ask on a discussion board if you have a vacuum regulator to sell perhaps? Thanks, Tommy

Make sure that vacuum hose to the water valve is plugged until you replace that valve. This hose was open to the atmosphere for who knows how long. I just recently acquired the fairly original vehicle and basically de-bugging the issues. I don't have any vacuum and all the hoses "appear" OK pending re-check. I need a vacuum tester ASAP. Thank you !, Tommy
