since my old valve was seized I've been looking for replacements, so far I've searched here and have seen references to mid $80's Hondas, an '85 Civic, there's new at OTGS ($69-ouch). One member (DESTEC) has rigged a solenoid valve up to his blower rocker switch, turning on blower either speed will also open valve, seems like a good idea

I came across this one early in a search, probably many like it:
Servo Heater Valve
Benefit: no mechanical cable to keep in shape, no risk of seizure transferring force to control slider and breaking stuff
Downside: another electrical device to keep happy,
Questions: the original mechanical valve is somewhat adjustable, (can open the valve a little or all the way) I wonder if this has any discernable effect on temperature control (I don't think so)?
So using a valve that is either completely open or completely closed won't matter?
Hooked up to blower switch:
How often, if ever would a guy have the valve open; heater core heated but the fan motor off? I can see maybe if you want a tad of defrost or some "ambient" heat. Just wonder from you long time GT drivers. I don't plan on driving mine all winter but I'm certain to see frosty mornings quite often.
PS old valve has been cleaned up and funtions but is pretty stiff, how much resistance is normal?
