The HVAC servo controls electrical, vacuum, and coolant flow functions. If the coolant flow valve isn't stuck (e.g. it only leak) you can bypass the servo coolant flow control and still use the servo for electrical and vacuum functions. My '79TD came this way with a manual shut-off valve in the coolant line. I lived in FL at the time so I left it off all the time but I suppose the PO opened the hood and manually set the valve as needed. Also, the older manual HVAC system used a manually operated valve (which may still be available) that was controlled by a push-pull cable that ran into the cabin. There is also a pricey (like $700) kit from Unwired Tools that replaced the servo completely but you have to be really committed to the car to spend that much. There were some articles on the servo some years back so I loaded them up on my site in case you want to read or download. Warning: the files are a couple megs each. http://kittrellcommunitywatch.dyndns.org/servo Many on this suite don't like George Murphy but he seems to be the expert on these servos. Maybe this helps.

I want to temporarily bypass the removed servo in my W116 so I can have some heat until I can either repair or replace it. I am planning to just plumb the heater core directly to the circulating pump (should act basically like the servo water valve is wide open) but do I need to jumper any of the electrical or vacuum connections to get the fan to run? Since defrost should be the failsafe I am thinking if I just plug all the ports on the vacuum connector and select the Defrost pushbutton on the console I should be able to get by with that?
